Migrating product analytics platforms is disruptive if not planned carefully — event naming changes, missing events during transition, team confusion about which platform to trust, and loss of historical context are common failure modes. We manage analytics platform migrations: documenting what exists, mapping old events to new implementations, running both platforms in parallel during validation, and managing the team transition so the new platform becomes trusted quickly.

Frequently Asked Questions

Partial migration is possible via data export, but format differences and platform-specific features make full migration complex. We typically recommend fresh implementation with historical reference retained in the old tool.
Typically 4–8 weeks — long enough to validate metric equivalence across a full monthly cycle including any seasonality. We define specific validation criteria before switching the team's primary tool.
Losing event parity — missing events that exist in the old platform. We conduct a comprehensive audit of all events in the old platform before designing the new implementation.
If the data layer is well-designed, often only the routing changes (different SDK calls), not the underlying event structure. In practice, migrations are also an opportunity to improve the taxonomy.
Depends on the quality of your current implementation. If the current analytics has known taxonomy problems, rebuilding with a new taxonomy during migration is more valuable than a like-for-like port.
