Goal: Move 25,000 contacts, zero downtime
A SaaS company had hit the ceiling of its starter CRM. What made switching complicated was everything living inside it: years of custom fields, activity logs, and renewal history the team relied on for every customer conversation.
Moving to a more capable platform meant getting all records across, with no downtime and nothing lost.
Action: Audit, clean, and migrate
We audited the source data before touching anything and found about 7% of records were duplicates or dead. We cleaned those first, then built a field-by-field mapping so custom data landed in the right place rather than a generic notes box.
The migration ran in staged batches over a weekend, with each batch validated before the next began.
Result: Full history intact, team live on Monday
All records moved across with full activity history intact, and the team logged in Monday to a system that already felt familiar. Renewal conversations picked up exactly where they had left off, and not a single customer noticed the switch had happened.
