In short Remqa runs four kinds of migration: CRM, ATS and recruiting CRM, legacy code, and data. Every migration follows the same five steps: map, test run, verify, cut over, and keep the old system read-only until the client signs off.

- CRM: Salesforce, HubSpot, Pipedrive, Zoho, Attio

- ATS: Bullhorn, Loxo, Recruit CRM, Greenhouse, Lever, Ashby

- Code: framework and language upgrades, monolith splits

- Data: spreadsheets and old databases into Postgres, BigQuery or Snowflake

Every migration has the same risk: something important gets left behind and nobody notices for a month. Remqa's forward deployed engineers run migrations end to end, use AI for the heavy lifting, and verify every record before you switch.

## How every migration runs
1 **Map.** Every object, field, owner, stage and file is mapped from old to new. You sign off on the map before anything moves.

2 **Test run.** A full trial migration into a sandbox or a copy of the new system, so problems show up before go-live, not after.

3 **Verify.** Record counts reconciled, relationships checked, and spot checks on real records with your team.

4 **Cut over.** A planned switch with a short freeze window, then a final delta sync for anything that changed during the test run.

5 **Keep the old system read-only.** Nothing is deleted until you are happy with the new one.

FAQ
## Common questions.

**Q: What kinds of migrations does Remqa do?**
CRM migrations, ATS and recruiting CRM migrations, legacy code migrations and data migrations into modern databases and warehouses.

**Q: How do you make sure nothing is lost?**
Every migration starts with a signed-off map and a full test run, then record counts and spot checks are reconciled before cutover. The old system stays read-only until you sign off.

**Q: Do you use AI for migrations?**
Yes, for mapping suggestions, cleaning messy data, matching duplicates and drafting code. Engineers review everything, and verification is done with plain counts and checks.
