MIGRATION OVERVIEW

Why teams migrate from Zendesk Sell to Microsoft Dynamics 365 Sales

There is no native migration path from Zendesk Sell to Microsoft Dynamics 365 Sales, requiring a fully custom, API-driven approach to transfer data between the two platforms. The fundamental data model differences are significant: Zendesk Sell uses a unified Contact object that must be split into separate Account and Contact entities in Dynamics 365, pipelines and stages must be recreated as Business Process Flows or Option Sets, and activities leverage polymorphic lookups in Dataverse rather than simple parent references. Custom work is required for OAuth 2.0 authentication setup via Microsoft Entra ID, recreating custom field definitions through the Dataverse Metadata API, re-encoding document files from expiring Zendesk download URLs, and executing a carefully sequenced, dependency-ordered migration across multiple phases.
KEY CHALLENGES

What makes this migration complex

These are the architectural mismatches and technical hurdles specific to a Zendesk Sell to Microsoft Dynamics 365 Sales migration.

Most Critical

Contact-to-Account/Contact Separation

Zendesk Sell's unified Contact object must be filtered by is_organization and split into distinct Account and Contact records in Dynamics 365, with parent relationships re-established using @odata.bind annotations.

Pipeline and Stage Recreation

Zendesk Sell pipelines and stages have no direct API-importable equivalent in Dynamics 365 and must be manually or programmatically recreated as Business Process Flows, Option Sets, or Status Reasons before deal migration can begin.

Polymorphic Activity Lookups

Tasks, calls, and notes in Dataverse use polymorphic regardingobjectid lookups that require entity-type-specific navigation properties, making activity association more complex than Zendesk Sell's simple resource_type/resource_id references.

Document and File Migration

Zendesk Sell provides only expiring download URLs for documents, requiring files to be downloaded in transit and re-uploaded as Base64-encoded Annotation records or routed to SharePoint/OneDrive integrations in Dynamics 365.

Custom Field Type Consistency

Custom field definitions must be fetched from Zendesk Sell per resource type and recreated as matching Dataverse columns via the Metadata API, with careful attention to type mapping between Zendesk field types and Dynamics 365 column types.

Dependency-Ordered Execution Sequencing

The migration must follow strict entity dependency ordering—Users, Pipelines, and Custom Fields first, then Accounts/Contacts, Leads, and Products, and finally Deals, Orders, and Activities—to ensure all lookup references resolve correctly.

MIGRATION RISK ASSESSMENT

Every migration risk, already solved

Migration between platforms is full of edge cases. Our engineers have identified every risk from Zendesk Sell to Microsoft Dynamics 365 Sales and built proven solutions for each one.

Migration Challenge ClonePartner Status
High Complexity —
Solved
Pipelines and Stages
There is no direct API import path for pipeline structures; they must be recreated through Dynamics 365 configuration tools or metadata APIs, with stage IDs and probability values carefully mapped to Option Sets or Business Process Flows.
Solved
Deals (Opportunities)
Deals depend on nearly every other migrated entity—Accounts, Contacts, Users, Pipelines, and Products—making them highly sensitive to any upstream mapping errors or missing references.
Solved
Products and Price Lists
Zendesk Sell's prices array must be decomposed into Dynamics 365 Price Lists and Price List Items, which involves complex metadata setup beyond simple product record creation.
Solved
Documents
Zendesk Sell provides only temporary expiring download URLs, requiring files to be downloaded during migration and re-uploaded as Base64-encoded Annotations or routed to SharePoint, with risk of data loss if URLs expire mid-migration.
Solved
Custom Engineering —
Handled
Users
Users cannot be created via API in Dynamics 365 and must be pre-provisioned in Microsoft Entra ID, requiring manual ID mapping between Zendesk Sell user IDs and existing systemuserids.
Handled
Accounts (Organizations)
Zendesk Sell organizations must be filtered from the unified Contact object and field-mapped to the Account entity, with all generated GUIDs stored for downstream contact and deal association.
Handled
Contacts (Persons)
Individual contacts must be separated from organizations, mapped to the Contact entity, and linked to parent Accounts using parentcustomerid_account lookups, adding relational complexity.
Handled
Orders and Line Items
Zendesk Sell's separate Order and Line Item objects must be migrated as Sales Orders and Order Products in Dynamics 365, requiring correct association to both Opportunities and Products.
Handled
Tasks and Calls (Activities)
Activities require polymorphic regardingobjectid lookups with entity-type-specific navigation properties, and call outcomes must be mapped to custom Option Sets that don't exist natively in Dynamics 365.
Handled
Custom Fields
Custom field definitions must be fetched per resource type, recreated as Dataverse columns with appropriate type mappings via the Metadata API, and validated before any data records referencing them can be imported.
Handled
Clean Transfer
Leads
Leads map directly between platforms with straightforward field correspondence, though owner assignment and status mapping require the pre-established user and custom field mappings.

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 Zendesk Sell and Microsoft Dynamics 365 Sales 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 conversation threads, attachments, and internal notes
  4. Syncing custom fields, SLAs, and macros 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 Zendesk Sell data and Microsoft Dynamics 365 Sales
  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 SLA 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 Zendesk Sell or Microsoft Dynamics 365 Sales exactly the same way—with unique automations and data. We customize every migration script to fit your exact workflow, tags, and triggers.

Our engineers adapt for:

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