CRM Migration
CRM migration is the process of moving contacts, deals, activity history, and configuration from one CRM platform to another without losing data or breaking active workflows.

What CRM migration involves
CRM migration moves a company's customer data and configuration from one platform to another: contacts, companies, deals and their stage history, notes, emails, attachments, custom fields, and often automations, permissions, and integrations. Unlike a simple data export, a real migration has to reconcile two different data models — the old system's fields, stages, and object types rarely map one-to-one onto the new one — and decide what to keep, merge, or drop.
The typical sequence is: audit the existing data and flag duplicates or stale records, map old fields to new ones, run a test import into a sandbox or trial account, validate record counts and spot-check key accounts, then do a full import and cut over. Running the old and new systems in parallel for a short window is common so nothing falls through during the switch.
Example
A team moving from a spreadsheet-based process to a CRM might export contacts to CSV, map "Company Name" and "Last Contacted" columns to the new system's fields, import in a test batch of 50 records to check for errors, then import the full list once field mapping is confirmed correct.
Why migrations go wrong
Most failed migrations aren't caused by the import itself — they're caused by incomplete field mapping or unclean source data. A field that holds free-text notes in the old system might need to become a structured dropdown in the new one, and if that mapping isn't planned in advance, the data either gets dropped or dumped into a catch-all field nobody uses. Duplicate contacts that existed in the old system get imported as duplicates in the new one unless a deduplication pass runs first.
The second common failure is treating migration as a one-time data dump instead of a configuration project. Deal stages, automation triggers, user permissions, and integrations with email or calling tools all need to be rebuilt, not just the underlying records. A migration that only moves data but skips this rebuild leaves a team with clean records and a broken workflow.
Why it matters when choosing a CRM
Migration cost and risk are a real, if often ignored, part of total cost of ownership. A CRM that locks data into a proprietary format, charges for data exports, or lacks a documented API makes a future migration slower and more expensive — which in turn makes it harder to leave if the platform stops serving the team well. Evaluating how easy data is to get out of a system, before committing to it, is as important as evaluating how easy it is to get data in.
