MIGRATION OVERVIEW

Why teams migrate from Kentico to Sitecore

The core problem
Migrating from Kentico (Xperience 13 or older) to Sitecore is a fully custom ETL operation — no native migration connector, import wizard, or vendor-provided tool exists between the two platforms. Kentico stores content across a relational SQL structure split among CMS_Tree, CMS_Document, and per-page-type coupled data tables, while Sitecore models all content as hierarchical Items defined by Templates. Bridging these architectures requires flattening Kentico's multi-table joins into structured payloads and pushing them into Sitecore as Template-mapped Items, with custom code required for every page type, field type translation, media transfer, taxonomy mapping, and referential integrity resolution. No part of this migration can be automated out of the box; every data entity requires explicit extraction logic, transformation rules, and Sitecore ingestion scripting.
Why this matters for your migration
KEY CHALLENGES

What makes this migration complex

These are the architectural mismatches and technical hurdles specific to a Kentico to Sitecore migration.

Most Critical

Relational-to-Item Architecture Gap

Kentico's three-table relational content model (CMS_Tree, CMS_Document, coupled data tables) must be flattened and re-expressed as Sitecore Template-based Items, requiring custom join logic and transformation code for every page type.

Blocks all downstream imports if mapped wrong

Page Type to Template Mapping

Every Kentico page type must be individually audited via CMS_Class, have a corresponding Sitecore template designed and deployed, and have its field types translated across incompatible type systems before any data can move.

Content Tree Structure Remapping

Kentico's NodeAliasPath hierarchy must be re-rooted into Sitecore's /sitecore/content tree structure, and high-volume nodes must be pre-configured as Sitecore Item Buckets to avoid severe Content Editor performance degradation.

GUID and Referential Integrity Resolution

Kentico uses NodeGUIDs for page-to-page relationships stored in the CMS_Relationship table, while Sitecore uses its own Item GUIDs, requiring a complete cross-reference remapping layer to preserve internal links without breakage.

Multilingual Content Reconstruction

Kentico stores each language variant as a separate CMS_Document row per node, whereas Sitecore uses per-Item language versions, requiring extraction and reassembly of all culture variants per content node before ingestion.

Media and Attachment Migration

Kentico stores media across filesystem or Azure Blob (media libraries) and database-stored page attachments (CMS_Attachment), both of which must be extracted separately and re-ingested as Sitecore Media Library items or Content Hub assets before content items can reference them.

MIGRATION RISK ASSESSMENT

Every migration risk, already solved

Migration between platforms is full of edge cases. Our engineers have identified every risk from Kentico to Sitecore and built proven solutions for each one.

High complexity
  • Page Content (CMS_Document / Coupled Tables)
    Every page type requires a custom three-table SQL join, a mapped Sitecore template, and field-level type translation, making this the most labor-intensive and error-prone entity in the migration.
    Solved
  • Page-to-Page Relationships (CMS_Relationship)
    Internal page references keyed on Kentico NodeGUIDs must be remapped to Sitecore Item GUIDs, requiring a maintained cross-reference table and post-ingestion link rewriting across all affected fields.
    Solved
  • Page Attachments (CMS_Attachment)
    Database-stored file attachments are not co-located with media library assets and require a separate extraction path from the CMS_Attachment table, with binary data retrieval and individual Sitecore media item creation for each file.
    Solved
  • Presentation and Layout Configuration
    Kentico's Page Builder widgets and MVC view assignments have no equivalent in Sitecore's rendering and layout system, meaning all presentation layer configuration must be rebuilt from scratch in Sitecore rather than migrated.
    Solved
Custom engineering
  • Content Tree Hierarchy (CMS_Tree)
    The NodeAliasPath structure must be re-rooted into Sitecore's content tree, and Item Bucket configuration must precede ingestion for any node exceeding 100 child items to prevent performance issues.
    Handled
  • Multilingual Content Variants
    Multiple CMS_Document rows per node (one per culture) must be extracted, grouped by NodeID, and re-ingested as Sitecore language versions, with risk of dropped or misassigned variants if culture codes do not align.
    Handled
  • Media Library Assets
    Media stored in filesystem or Azure Blob must be inventoried, transferred, and re-ingested as Sitecore Media Library items before content migration runs, or content item media references will be broken at ingestion time.
    Handled
  • Taxonomy and Categories (CMS_Category / CMS_DocumentCategory)
    Kentico categories are bound to CMS_Document via a junction table and must be recreated as Sitecore taxonomy items in the content tree, with tag field assignments re-mapped per migrated item.
    Handled
Clean transfer
  • Workflow and Publishing State (DocumentWorkflowStepID)
    Workflow step data can be extracted via SQL and used to filter or flag items by publish state, but Sitecore's workflow model is independently configured and states do not transfer directly, reducing migration risk to classification only.
    Clean
  • Version History
    Full version history is accessible via SQL extraction but is rarely migrated to Sitecore due to model incompatibility; most projects migrate only the current published version, making this a scoping decision rather than a technical blocker.
    Clean

What does an Engineer-led migration mean anyway?

Speed & Accuracy: Our Blended Method

We blend automation (smart scripts, bulk APIs) with human expertise for speed without risk. Our engineers manually check every mapping, validation, and exception.

You get:

  1. Speed of automation for bulk record migration
  2. Precision of engineers verifying integrity and business logic
  3. Pilot migrations and sandbox testing to catch issues early
  4. Real-time validation reports and rollback readiness
Result: 50x faster migrations than manual imports — with near-zero error rates.

Handling the Tricky Tech and API Details

The Kentico and Sitecore APIs each behave differently, which is where our engineers shine. We build custom logic to handle the data quirks where generic tools typically break.

We handcraft API logic for:

  1. Field mapping and transformation
  2. Pagination, rate-limit handling, and throttling
  3. Preserving content relationships, media, and revision history
  4. Syncing custom fields, taxonomies, and templates without breaking structure
Our scripts: Natively retry failed calls, re-queue large attachments, and ensure data parity.

No Guesswork

We don't just promise smooth migrations—we measure and prove them. Every client receives a Migration Validation Report with all metrics.

Typical results across projects:

  1. 100% record-count parity between your Kentico data and Sitecore
  2. Zero downtime during staged cutovers
  3. 99.9% attachment integrity (verified via checksum)
  4. Full automation and preservation of all business rules
Our standard: Includes full SEO and redirect preservation and 30 days of engineer-assigned support post go-live.

We Adapt to Your Setup (Not the Other Way Around)

No two teams configure Kentico or Sitecore exactly the same way—with unique content models and data. We customize every migration script to fit your exact workflow, taxonomies, and templates.

Our engineers adapt for:

  1. Custom fields, content types, and workflows
  2. Multi-site or multi-language setups
  3. Historical imports and partial (date-based) migrations
  4. Integration re-mapping for search, analytics, or forms tools
The promise: If your data doesn't fit a standard template, we build one just for you.

Kentico → Sitecore

6 questions
Do Kentico BizForms migrate to Sitecore, and what gets lost?
BizForms are migrated as Sitecore Items, but the mapping is a workaround because Sitecore Forms stores structure differently: field types, validation rules, and submission routing all need to be manually reconfigured in the target environment. More critically, form submission data cannot be imported through the standard Kentico API; retrieving it requires direct database access or a custom endpoint, which must be arranged before the migration starts. The form definitions can land in Sitecore, but treat the submission history as a separate data extraction task that needs explicit scoping.
How do Kentico headless Content Types and Content Items come across in Sitecore?
Kentico headless Content Types map to Sitecore Templates and headless Content Items are stored as standard Sitecore Items. Neither has a native headless equivalent in Sitecore's data model, so both are workarounds. Once the data lands, headless content delivery in Sitecore (for example via XM Cloud's GraphQL Edge API) requires additional setup that is outside the data migration: configuring rendering hosts, content resolvers, and publishing targets. ClonePartner moves the structured data; the headless delivery layer is part of your implementation project.
Which version of Kentico do I need to be on before migration can start?
For migrations sourced from Kentico Xperience 13, the Management API is the most complete pathway and requires version 13.0.64 (Refresh 5) or newer; earlier patch levels have API surface gaps that can silently skip records. Kentico versions 12 and earlier relied on the CMS.DataEngine .NET layer rather than REST, which requires a different extraction approach. Confirm your exact version during scoping. Note that Kentico Xperience by Kentico (the current SaaS-first product) has a different API surface again, so the version check is the first step in every engagement.
What happens to URL redirects and aliases when they move to Sitecore?
Kentico URL aliases are migrated as Sitecore Redirect Items under the workaround model, because Sitecore has no dedicated redirect object type. After import, those items may conflict with the target environment's URL structure (particularly on XM Cloud or multisite setups), so each redirect destination GUID must be verified against the migrated item tree before the site goes live. Redirect validation is a post-migration manual task; ClonePartner's referential integrity checks flag broken destination links, but resolving conflicts in the URL structure is your team's responsibility.
Will user passwords come across from Kentico?
No. Kentico does not expose hashed passwords through its API, so all migrated user accounts arrive in Sitecore without a password set. Every user will need to complete a password reset before they can log in. Usernames, roles, and role assignments migrate directly; only the credential itself is lost, and this is a platform-level limitation with no workaround.
What do I need to manually rebuild in Sitecore after the content data lands?
Several things cannot be carried over by any migration tool: item-level security permissions (access rights are stored separately in Sitecore and are commonly missed), computed fields and search index data (these must be rebuilt by triggering a full index rebuild), and any layout or rendering assignments (stored as XML blobs that are tightly coupled to your Sitecore implementation). Kentico web part and widget configurations are also not portable because they are bound to .NET assemblies that don't exist in Sitecore. Relationships between pages and categories must be re-established after both sides have been migrated, since Kentico's page-category links are a separate migration step from the records themselves.

Before you start

4 questions
Do I need professional help for this migration?
Yes. Professional help ensures proper field mapping and preservation of relationships between records. Our engineer-led approach catches edge cases that automated tools miss.
Does ClonePartner provide guidance before committing?
Yes. We provide a free consultation and assessment. We'll review your data structure, discuss your requirements, and provide a detailed migration plan and fixed-price quote before you commit to anything.
Do you use an off-the-shelf tool to migrate from Kentico to Sitecore, or is this built for our data?
It is built for your data. Each migration is a set of custom scripts written for your data model, not a generic import tool. That is also why we start with a sample migration: you see your own records in Sitecore before the full migration is committed.
Can we see a sample of our Kentico data migrated to Sitecore before the full migration runs?
Yes. We run a sample migration on your own data first, so you can review how your records look in Sitecore before the full migration goes ahead. We run validation scripts to confirm the record counts match your source, and you check the sample against your source records; if a field is missing or mapped wrong, or anything else needs adjusting, we fix it in the migration scripts and re-run the sample as many times as you need. The full migration only runs after you've approved the sample. On projects delivered in phases, each phase gets its own sample migration for you to approve.

Data & mapping

7 questions
Will original ownership, authorship and created dates be preserved?
Yes. Created-time metadata is carried across, and ownership and authorship are carried across where the original users are set up in Sitecore. Where Sitecore cannot store one of them natively, it is kept as embedded metadata on the migrated record.
If the new system can't natively support an old record type, what are my options?
We handle it case by case. While mapping your data, we identify every record type without a direct counterpart in Sitecore, review sample records from it and propose how it can be represented, based on what Sitecore supports: map it to the closest native object, create a custom field or object, fold it into the parent record as text or a note, attach it as a file, or keep it in a read-only archive. You choose the approach, we write the migration scripts to place the data there, so it comes across in the form you choose instead of being left behind, and you see how it looks in a sample migration before we run the full set.
We've built custom modules and integrations on Kentico. Can you migrate their content to Sitecore?
We migrate the content and data your custom modules hold, as long as it can be read from Kentico programmatically. Every migration we run is written as custom code for that project rather than pushed through an off-the-shelf tool, so unusual module data is not a blocker. During scoping we review each custom module and integration with you and agree how it will be handled before any work is committed.
Will the migration set off automations or send emails or notifications to customers, our team or anyone else?
No. Before the sample or full migration starts, we confirm with you that nothing in Sitecore will send messages about the migrated data: we import with notifications switched off wherever Sitecore allows it, and either pause any automation that could send them for the migration window or give it a condition, such as a suppression tag, that skips migrated records, which lets your live automations keep running for new records. We only proceed once you have confirmed it. If you want anyone told about the move, that message is sent separately, once the migrated data has been checked.
Can you migrate data that Sitecore can't take in through an API?
In many cases, yes. Where something can't be written through an API, we recreate it through Sitecore's user interface where the interface allows it, and where that work is repetitive we script and automate it. We tell you up front which items are handled this way, because recreating them through the interface can add time to the schedule.
What happens if Sitecore requires fields our Kentico data doesn't have?
We check the destination for required fields your source data cannot fill and bring each one to you before those records are migrated. Together we agree how each one is handled, such as a mapping from an existing field, a default value, or, where Sitecore lets that field be made optional, setting it to not required for the migration so you can make it required again once the migration is complete. The migration then runs with that rule applied, so no records are rejected or left behind.
Can you change our URL structure when we move from Kentico to Sitecore, such as moving a blog or docs from a subdomain onto our main domain?
Yes, where Sitecore and your site's front end support the structure you want. Each page is created in Sitecore by the migration, so it can be given its new address, for example a blog moved from a subdomain to a path on your main domain, and you get a map of every old URL to its new one so redirects can be set up from the old addresses wherever they are served.

Timeline & downtime

2 questions
How long does the Kentico to Sitecore migration take?
Most migrations complete within 1–5 business days, depending on data volume and complexity; very large migrations, such as several hundred thousand records, take longer. We provide a detailed timeline after the initial assessment and can often complete small migrations in under 24 hours.
Will there be downtime when migrating from Kentico to Sitecore?
No. Our migration process is designed for zero downtime. Kentico stays fully operational throughout: the bulk migration runs in the background and the cutover is fast, so there is no disruption to your live business operations.

Security & access

1 question
Can we whitelist a single IP instead of opening our network to your migration tool?
Yes. All migration traffic runs through a centralized system using one fixed IP, which your IT team can whitelist instead of opening broader network access.

Pricing

1 question
Is migration pricing a flat fee, or does it scale with data volume?
It's a flat fee with no hidden costs. The price we agree with you for your scope is the price you pay, and small variances in the final volume, a bit more or less, are included.

After go-live

5 questions
How do I validate that everything migrated correctly?
Every client receives a Migration Validation Report with comprehensive metrics including record-count comparison, attachment integrity verification via checksum, and full audit logs of the migration run, showing every record created, skipped or failed. If any item didn't come across, the report names each one, the specific reason, and how to bring it across if you want it there. We also offer unlimited sample migrations, so you can check your data before the full migration runs.
What support do you provide after the migration goes live?
At ClonePartner, we consider ourselves your partners in this journey. We take full accountability for your migration's success. Once your migration goes live, we provide 30 days of comprehensive post-migration support as standard, and longer support, such as 60 or 90 days, can be agreed for your project. During this period, we help with anything related to your migrated data, so your migration is a complete success.
Will we get a migration report and a mapping sheet linking old record IDs to new ones?
Yes. We provide a comprehensive migration report along with an ID-mapping sheet that links each old Kentico record ID to its new ID in Sitecore. This ensures full traceability, simplifies post-migration verification, and helps your team validate that records have been migrated accurately.
After migration, do I contact ClonePartner or the platform's own support if something looks wrong?
ClonePartner is the contact for anything about the migrated data itself. Questions about the platform itself, such as how its features and settings work, go to the platform's own support or to whoever administers it for you.
Will our existing Kentico page URLs and links keep working after we move to Sitecore?
They can, through redirects and link rewriting. Links between your own pages are updated to point at their new URLs as part of the migration, and the files and images your pages use are re-hosted on Sitecore, wherever it can host them, with their links rewritten. For every old URL we give you a map to its new address, so redirects can be set up where your site is served and old bookmarks, search results and external links open the right page.
