Sitefinity to Tilda Migration

MIGRATION OVERVIEW

Why teams migrate from Sitefinity to Tilda

The core problem

Migrating from Sitefinity to Tilda presents a fundamental architectural conflict: Sitefinity is a full-featured enterprise .NET CMS with a relational data model, OData REST API, dynamic content types, and programmatic control over every content object, while Tilda is a block-based, presentation-first website builder with no write API for pages. The critical constraint shaping the entire migration is that Tilda's API is read-only — pages and blocks cannot be created programmatically, limiting automated ingestion strictly to blog and news content via Feeds CSV import and product data via Catalog CSV import. All other content — static pages, forms, navigation structures, media libraries, and reusable content blocks — must be manually reconstructed in Tilda's visual block editor. Custom work is required to extract content via Sitefinity's OData endpoints, transform and flatten relational data structures into Tilda-compatible flat formats, host media assets on a publicly accessible CDN, and perform a full manual rebuild of all non-structured page content.

Why this matters for your migration

KEY CHALLENGES

What makes this migration complex

These are the architectural mismatches and technical hurdles specific to a Sitefinity to Tilda migration.

Most Critical

No Programmatic Page Creation

Tilda's API is read-only, meaning every static page, landing page, and complex layout must be manually rebuilt in Tilda's visual block editor with no automation pathway available.

Blocks all downstream imports if mapped wrong

Relational Data Flattening Required

Sitefinity's Dynamic Module fields — including related data (one-to-many), related media, and classification taxonomies — have no foreign key equivalent in Tilda and must be resolved and flattened to plain text or URL references before CSV generation.

Rich HTML Content Cleanup

Sitefinity stores rich text as HTML containing internal URL patterns, proprietary tags like sfref, embedded widgets, and .NET-specific attributes that must all be stripped and rewritten before content can be imported into Tilda Feeds without rendering failures.

Media Hosting and URL Remapping

Tilda's CSV importers require publicly accessible image URLs, so all media stored as database binary blobs or behind authenticated Sitefinity endpoints must be downloaded, re-hosted on a public CDN, and remapped before CSV generation.

Lossy Dynamic Module Field Mapping

Sitefinity's Module Builder supports over ten field types including numeric, date-time, address, and relational fields, while Tilda Custom CMS Feeds offer only five field types, resulting in irreversible data type degradation for most non-text fields.

Permanent Loss of Enterprise Features

Sitefinity capabilities including personalization, workflow and approval chains, field-level role-based access control, content version history, and multisite management have no structural equivalent in Tilda and cannot be migrated or approximated.

MIGRATION RISK ASSESSMENT

Every migration risk, already solved

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

High complexity

Static Pages

No automated migration pathway exists — every static page, landing page, and homepage layout must be fully reconstructed by hand in Tilda's visual block editor, representing the largest manual effort of the entire migration.

Solved
Dynamic Module Items

Sitefinity's Module Builder supports over ten field types that map lossily to Tilda's five Custom CMS Feed field types, requiring all relational, numeric, date, and address fields to be flattened into plain text with permanent data fidelity loss.

Solved
Media Libraries

Images stored as database binary blobs or behind authenticated Sitefinity endpoints cannot be directly referenced by Tilda's CSV importer and must be individually downloaded, re-hosted on a public CDN, and have all content URLs remapped before import.

Solved
Forms

Sitefinity forms have no automated import pathway into Tilda and must be manually rebuilt as Tilda Form Blocks, with all field configurations, validation rules, and submission routing recreated by hand.

Solved
User Accounts / Roles

Sitefinity's user accounts, role-based access control, and field-level permissions have no equivalent in Tilda and cannot be migrated — only Tilda Members can be imported, subject to a hard platform limit of 100 users per day.

Solved
Workflows / Approvals

Sitefinity's content approval workflows, draft routing, reviewer assignment, and publish gating have no structural equivalent in Tilda and are permanently lost, requiring organizations to establish entirely new editorial governance processes outside the platform.

Solved

Custom engineering

Blog Posts / News Items

Automated CSV import into Tilda Feeds is possible, but rich HTML content requires significant cleanup to remove Sitefinity-specific markup, internal URL references, and proprietary tags before import will succeed without rendering failures.

Handled
Products / E-commerce

Tilda Catalog supports CSV import for product data, but Sitefinity product fields that include relational data, complex pricing structures, or non-standard attributes must be flattened and may not map cleanly to Catalog's field schema.

Handled
Taxonomies (Tags, Categories)

Sitefinity taxonomy classifications must be manually pre-created as categories in Tilda Feeds before CSV import, and the relational classification references in content records must be resolved and converted to matching category names during transformation.

Handled
Events

Events can be partially migrated by mapping to Tilda Feeds via CSV import, but Sitefinity event-specific fields such as date-time, location address, and related data must be flattened to text strings with loss of native field typing.

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:

Speed of automation for bulk record migration
Precision of engineers verifying integrity and business logic
Pilot migrations and sandbox testing to catch issues early
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 Sitefinity and Tilda 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:

Field mapping and transformation
Pagination, rate-limit handling, and throttling
Preserving content relationships, media, and revision history
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:

100% record-count parity between your Sitefinity data and Tilda
Zero downtime during staged cutovers
99.9% attachment integrity (verified via checksum)
Full automation and preservation of all business rules

Our standard: Includes full SEO and redirect preservation and 48 hours of engineer-assigned support post go-live.

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

No two teams configure Sitefinity or Tilda 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:

Custom fields, content types, and workflows
Multi-site or multi-language setups
Historical imports and partial (date-based) migrations
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.

FAQ

Frequently Asked Questions

Everything you need to know about migrating from Sitefinity to Tilda. Can't find what you're looking for? Talk to our team.

Can I migrate Sitefinity pages to Tilda automatically?

Not in the way most teams hope. Tilda's API is read-only — it has no endpoints for creating pages or content programmatically. Blog and news posts can be bulk-imported into Tilda Feeds via CSV, and product data can go into Tilda Catalog via CSV. All pages, forms, and layouts must be manually rebuilt in Tilda's block editor.

How do I extract content from Sitefinity for migration?

Use Sitefinity's OData REST API (available in version 10+). All content types are available at /api/default/{entity} endpoints (e.g., /api/default/newsitems, /api/default/blogposts). Paginate with $top and $skip parameters. The default page size is 50 items per query.

What is the page limit in Tilda?

Tilda limits all plans to 1,000 pages per project. However, Tilda Feeds posts do not count against this limit — each feed supports up to 5,000 posts and a project can hold up to 20 feeds. Route high-volume content through Feeds to stay within the cap.

How do I handle 301 redirects when moving to Tilda?

Tilda supports 301 redirects, but only within the same domain and only from non-existent pages. For cross-domain redirects or large redirect sets (tens of thousands of URLs), use external infrastructure like Cloudflare Workers or registrar-level forwarding.

How long does a Sitefinity to Tilda migration take?

A small site under 50 pages typically takes 1–2 weeks. A medium site (50–200 pages) takes 3–6 weeks. Large sites with 200+ pages can take 2+ months. The bottleneck is always the manual page rebuilding in Tilda's editor, not the content extraction.

How long does the Sitefinity to Tilda migration take?

Most migrations complete within 1–5 business days, depending on data volume and complexity. We provide a detailed timeline after the initial assessment and can often complete small migrations in under 24 hours.

Will my team lose access to Sitefinity during the migration?

No. Your source system remains fully operational throughout the entire migration. We run the migration in the background with zero downtime to your current operations.

Will there be downtime when migrating from Sitefinity to Tilda?

No. Our migration process is designed for zero downtime. We use a staged approach with background sync and a fast cutover, ensuring no disruption to your live business operations.

How do I validate that everything migrated correctly?

Every client receives a Migration Validation Report with comprehensive metrics including record-count parity, attachment integrity verification via checksum, and full audit logs. We also offer unlimited sample migrations so you can verify before committing.

Do I need professional help for this migration?

While simple migrations can sometimes be handled in-house, professional help ensures zero data loss, proper field mapping, and preservation of relationships between records. Our engineer-led approach catches edge cases that automated tools miss.
