Salesforce to Zoho CRM Migration

Migrated more than 2 million records from Salesforce to Zoho CRM while Salesforce stayed live for day-to-day work.

How the data moves—and what can fail.

Salesforce needed to remain active during the initial move to Zoho CRM so day-to-day operations could continue while the migrated data was validated.

Project flow

Salesforce export
Structured exports across six related modules
Clean and map
Deduplication, normalisation, field mapping, and custom fields
Staged Zoho import
Initial load while Salesforce remained operational
Validated records
Relationships and source record IDs preserved for reconciliation

How failures are handled

Salesforce record IDs preserved for traceability and later attachment work
Module relationships checked to maintain referential integrity
Required fields, dates, and picklist values normalized before import
Staged migration kept day-to-day CRM operations available during validation

The problem

More than 2 million records had to move from Salesforce to Zoho CRM without losing module relationships or the source IDs needed for later attachment work. Salesforce also had to remain available during the initial import so day-to-day work could continue while the Zoho data was checked.

What moved

The migration covered six CRM modules:

Leads: 14,313
Contacts: 5,979
Accounts: 4,162
Opportunities: 17,244
Products: 241
Tasks: 182,070

How I prepared the data

Exported each Salesforce module in a structured format
Removed duplicate and invalid records
Normalised dates and picklist values for Zoho CRM
Checked required fields before import
Mapped Salesforce fields to existing and custom Zoho fields

How I preserved relationships

Salesforce record IDs were stored in Zoho CRM so records could be traced back to their source. Those IDs also support later attachment migration, reconciliation, and checks between related modules.

How the import was staged

The first full import ran while Salesforce remained the active CRM. This gave the team time to check the Zoho records, correct mapping issues, and prepare for the final changeover without pausing normal CRM work.

Result

More than 2 million records moved across six CRM modules while Salesforce remained available for day-to-day work. Salesforce IDs and module relationships were retained for validation and later attachment migration.
