Import2 or a CSV import?
The built-in import lives on the Leads and Customers pages, and
has a downloadable template so the columns line up. For anything with history and
relationships behind it, Import2 is far less painful.

Import2 offers a free sample migration that completes in under 15 minutes. Do this before the full run, every time.

1
Check pipeline stages
Stage names from the old system may not match yours. Fix them, and confirm your win and
lost stages are still flagged — reporting depends on it. See
Leads and pipeline.
2
Check ownership
Imported records need owners who exist here. Unowned customers do not benefit from
sticky assignment.
3
Spot-check phone numbers
Numbers without country codes will not match incoming WhatsApp conversations to the
right customer.
