How to Plan a Salesforce Data Migration Without Downtime

How to Plan a Salesforce Data Migration Without Downtime

Salesforce data migration planning prevents the #1 cause of implementation failure: dirty data imported into a clean system. The process: audit source data (2-3 days), build field mapping (3-5 days), design transformation rules (2-3 days), develop migration scripts (5-7 days), run test migration (2-3 days), validate with business users (2-3 days), execute production cutover (1 day). Total: 3-4 weeks. The most critical step: deduplication BEFORE migration — most legacy CRMs have 15-30% duplicate records that compound if imported. See: Data Migration Best Practices and SF Implementation Timeline.

How It Works in Practice

Enterprise implementations follow structured progression: assessment (2-4 weeks), design (2-4 weeks), build (4-12 weeks), stabilization (2-4 weeks). Total: 10-24 weeks. Organizations that skip assessment spend 40-60% more due to mid-build misalignment.
