Records migrating from an old system to a new system, representing CRM data migration

What goes wrong during CRM data migration

Most CRM migrations rely on CSV exports, import wizards, and manual field mapping. Records get lost, custom fields disappear, and the old and new systems fall out of sync within days.

Archive icon representing data lost through CSV exports

CSV exports strip relationships and history

Export contacts from Salesforce, import to HubSpot, and the deal associations are gone. Notes, activity logs, and linked companies don't survive the CSV round-trip. You end up with flat records.

Custom fields vanish in the new CRM

Your old CRM has custom fields for lead_score, contract_value, and renewal_date. The import wizard skips what it can't match. Nobody notices until a rep finds empty fields weeks later.

Old and new CRM drift apart after migration day

You migrate on Friday, switch Monday, and by Wednesday the old CRM has new contacts from ongoing campaigns. Nobody re-migrated them. Now two systems have different data with no way to reconcile.

Connect both CRMs as source and destination

Authenticate your old and new CRM with API keys. Oneprofile treats each CRM as both a source and destination. No CSV exports, no import wizards, no third-party migration tools.

Backfill all historical records on day one

The first sync processes every contact, company, and deal from your old CRM. Your new CRM starts with complete data from day one, not a partial CSV import with missing fields.

Run both CRMs in parallel during transition

Keep both CRMs synced while your team ramps on the new one. Records created in either system show up in both. When the cutover is complete, disconnect the old CRM.

If a record fails to migrate (field type mismatch, rate limit, missing required value), it's captured with full error context. Fix the mapping, reprocess, and the record syncs.

How CRM data migration works with Oneprofile

Five steps from connected CRMs to fully migrated data. No CSV files, no code, no migration consultants.

Step 1

Connect your old and new CRM

Authenticate both CRMs with API keys. Oneprofile validates credentials against the live API before saving. Each CRM is connected as both a source and a destination.

Step 2

Choose record types and matching key

Map Contacts to Contacts, Companies to Companies, Deals to Deals. Select email or domain as the matching key so Oneprofile pairs records correctly across both CRMs.

Step 3

Map fields between CRMs

Map first_name, company, deal_stage, lifecycle_stage, and custom fields. Oneprofile creates custom properties in the destination CRM automatically when they don't exist.

Step 4

Run the initial backfill

Start the first sync in Update or Create mode. Oneprofile processes all historical records from the old CRM and writes them to the new one. Review record counts and spot-check key fields.

Step 5

Keep both CRMs in sync, then cut over

Set a 15-minute sync schedule. Both CRMs stay current during the transition. When your team is ready, disconnect the old CRM. Your new CRM is already connected to every other tool.
