Quick answer: To migrate CRM data safely, export from your old system, clean and de-duplicate the data, map fields to your new CRM, run a small test import, then do the full import and verify record counts. Back up the original export before you start — it is your safety net.
Migrate carefully, not quickly
CRM data is your business memory — every contact, deal and conversation. A rushed migration can silently drop records, mangle fields or create duplicates you spend months untangling. The good news: a disciplined, staged process makes migration safe and even improves your data along the way.
The 6-step migration process
| Step | What to do |
|---|---|
| 1. Back up & export | Export to CSV/Excel; keep the original safe |
| 2. Clean & de-duplicate | Remove dead leads and duplicates |
| 3. Map fields | Match old columns to new CRM fields |
| 4. Test import | Import a small batch first |
| 5. Full import | Import the rest once the test is clean |
| 6. Verify | Check counts and key fields |
Cleaning your data first
Migration is the best time to declutter. Before importing, remove obvious duplicates, drop dead or invalid leads, standardise formats (phone numbers, states, dates), and fill or flag critical blanks. Importing clean data means your new CRM starts trustworthy instead of inheriting years of mess.
Never delete data from your old CRM until the new one is verified and in daily use. Keep the original export file until you are completely confident — migrations occasionally need a second pass.
Mapping fields correctly
Every column in your export must map to a field in the new CRM. Match standard fields (name, email, phone, company) first, then create custom fields in the new CRM for anything without a home — loan amounts, policy numbers, referral sources. Dropping unmapped columns is how data quietly disappears. TatvaCRM’s import tool maps columns visually and lets you create custom fields inline, so nothing is lost. See migrating from Excel to CRM for spreadsheet specifics.
Verifying the import
- Compare counts: records imported should match records exported (minus removed duplicates).
- Spot-check records: open a sample and confirm every field landed correctly.
- Check relationships: contacts still linked to the right companies and deals.
- Confirm owners & tags: assignments carried over as intended.

Frequently asked questions
› How do I migrate data to a new CRM?
Follow six steps: back up and export your data from the old system, clean and de-duplicate it, map old fields to new fields, run a small test import, verify the results, then do the full import and check record counts. Always keep the original export as a safety net.
› How do I avoid losing data during a CRM migration?
Back up the original export before touching anything, migrate in a test batch first, and verify record counts and key fields after each import. Never delete data from the old CRM until the new one is confirmed complete and in use. A staged approach prevents irreversible mistakes.
› What data should I migrate to a new CRM?
Migrate active and relevant records: current contacts, companies, open deals, recent activities and any custom fields you rely on. This is the perfect moment to leave behind dead leads, duplicates and stale data rather than carrying clutter into the new system.
› How do I map fields between two CRMs?
List every field in your export, then match each to a field in the new CRM. Create custom fields in the new CRM for anything without a match. TatvaCRM's import tool lets you map columns to fields visually and create custom fields inline, so nothing is dropped.
› How long does a CRM migration take?
For a small business, a clean migration can take a day or two: a few hours to export and clean, and a test plus full import. Complex migrations with lots of custom data and history take longer. Clean data is the biggest factor in how smoothly and quickly it goes.
› Can I migrate to TatvaCRM from another CRM?
Yes. TatvaCRM supports CSV and Excel import with visual field mapping, custom-field creation, owner and tag assignment, and saved mappings for repeat imports. You export from your current CRM, map the columns, run a test batch, then import — with your original file kept as backup.
