Data Migration from Zoho CRM to Bitrix24
Once we had a client who, after a self-attempted migration, lost all relations between deals and contacts. Recovery took three weeks and required manual archival review. Switching from Zoho CRM to Bitrix24 isn't just copying records. Differences in architecture, API, and business logic often come as a surprise. We offer turnkey migration: from analysis to employee training. Our engineers are certified and have over 10 years of Bitrix24 experience, with more than 50 CRM migration projects completed.
Why Migration from Zoho to Bitrix24 Is Not Trivial
Zoho CRM uses its own role model and extended field types. For example, Subform and Formula have no direct counterpart in Bitrix24. Without proper mapping, you can lose relationships between records or face duplication.
Another challenge is the API. The Zoho CRM API limits 200 records per request, critical for catalogs of 100,000+ records. Slow export drags migration to weeks if pagination is not optimized. We use cursor pagination to bypass this limitation, speeding up the process threefold compared to standard approaches.
How We Migrate Data: Process and Technologies
Source Analysis and Mapping Design
The first step is auditing the current Zoho structure: modules, custom fields, relationships, data volume. We create a mapping map. Standard modules are migrated according to the table:
| Zoho Module | Bitrix24 |
|---|---|
| Lead (unconverted) | Lead |
| Contact | Contact |
| Account | Company |
| Deal | Deal |
| Task | Task |
| Event | Activity type "Meeting" |
| Call | Activity type "Call" |
| Note | Comment |
Custom Zoho modules have no direct counterpart. We convert them into custom entities (On-Premise configuration) or emulate via smart processes and high-load blocks.
Development and Testing
We write scripts in PHP 8.1+ using Composer. For working with Bitrix24, we use REST API. A test migration on a data copy reveals errors before launch. At this stage, we handle custom fields: Formula is replaced by robots, Subform by separate CRM entities, Multi-select Lookup by multiple fields.
Example from practice: a client with a catalog of 150,000 products and 30 custom fields. A test migration revealed 12% duplicate records due to mismatched uniqueness fields. We rewrote the mapping, adding external_id from Zoho, and the retest showed 0% duplicates.
Launch and Support
After the final migration, we check the integrity of relationships, record counts, and business processes. We guarantee data integrity and provide a week of post-migration support. The result is a fully operational system with correct relationships.
What to Do with Custom Modules?
Custom Zoho modules (e.g., Training or Inventory) have no counterpart in Bitrix24. We emulate them via smart processes or high-load blocks. For role models, we configure permissions manually based on the client's documentation. There is no direct access rights migration.
How We Guarantee Data Integrity
We use a three-stage check: test migration on a copy, automatic comparison of record counts and fields, manual spot-check of key deals. To date, no project has led to data loss — that's our reputation.
What's Included in the Work
- Detailed migration plan with timeline
- Field mapping (standard and custom)
- Migration script development
- Test and final migration
- Employee training on Bitrix24
- Documentation on settings and processes
Typical Migration Timelines
| Volume | Modules | Timeframe |
|---|---|---|
| Up to 20,000 records, standard modules | 4 modules | 2–4 weeks |
| 20,000 – 100,000 records, custom fields | 6–10 modules | 4–8 weeks |
| 100,000+ records, custom modules, subforms | 10+ modules | 2–4 months |
Typical Mistakes and How to Avoid Them
-
Record duplication — due to mismatched uniqueness check fields. We use custom
external_id. - Relationship loss — if parent object references are not transferred. Relationship mapping is mandatory.
- Zoho custom scripts not transferred — their business logic is recreated in Bitrix24 via robots or custom handlers.
