Prepare an inventory
- Export performance baselines by placement, geography and creative.
- Save blocklists and eligible audience lists.
- List trackers, payment tools and other integrations.
- Document existing supply agreements and ask which connections can be supported.
Test before switching
Recreate representative campaigns and run them alongside your existing setup. Check tracking, costs, conversion attribution, audience imports and source quality against your baseline.
Roll out gradually
Move the remaining campaigns only after the tests are reliable. Keep historical exports: a migration does not automatically transfer all prior statistics or account settings.
