From naming convention disasters to premature SDK removal — these are the most expensive migration errors and how to avoid every one of them.

The Migration Challenge

Switching MMPs is one of the most stressful projects a growth team can undertake. The fear of data loss keeps many teams locked into tools they've outgrown. But with proper planning — and the right checklist — migration can be smooth and data-loss-free.

⚠️ The #1 cause of data loss during MMP migration is poor naming convention alignment between old and new platforms. Always document your campaign naming structure before touching the SDK.
