Pre-Migration Audit and Planning
Before any migration, conduct a thorough audit of existing data: client profiles, communication logs, KYC documents, trading history, and custom fields. Map every data element from the source CRM to the target system. Identify data that needs transformation, fields that have no direct equivalent, and records that require cleanup before transfer.

The Migration Process
Execute migration in phases: first static data (client profiles, documents), then dynamic data (trading accounts, balances), and finally historical data (communications, notes). Run the new CRM in parallel with the old one for at least two weeks, comparing data consistency daily. Automated validation scripts should verify record counts, field integrity, and relationship mappings.
Post-Migration Verification
After cutover, perform comprehensive testing: verify client logins, check that automated workflows trigger correctly, confirm reporting accuracy, and ensure all integrations with MT servers and payment systems function properly. Keep the old system accessible in read-only mode for at least 90 days as a safety net.
