Use case - migration
Migrate to Amplitude without losing your history
A botched migration creates a permanent asterisk on every report that spans the cutover date, and the team that fought hardest against switching tools gets to say 'I told you so' for years.
In short
We map your existing platform's events and properties to Amplitude's schema and run both systems in parallel before cutover, so there's no gap where 'we don't know what happened last quarter' becomes the answer to every year-over-year question. History that was trustworthy before the migration stays trustworthy after it.
The situation
You've decided to move to Amplitude from GA4, Mixpanel, or Adobe Analytics, but you're worried the switch means losing every historical comparison you rely on.
What we implement
We map your source platform's events and properties to Amplitude's schema and run a parallel-tracking period before cutover, reconciling the two systems' numbers against each other - what's called migration parallel-run validation - so continuity is proven, not assumed.
What you get
- Year-over-year reporting that survives the tool switch instead of starting over
- A reconciled, documented gap analysis instead of an unexplained discontinuity
- Team confidence in the new platform because the numbers were checked, not just trusted
Illustrative
A team migrating off a platform with a different default session definition might find, during the parallel-run period, that a metric they assumed would carry over cleanly needs a documented adjustment - catching that during the overlap window, rather than a quarter later, is the entire point of running the two systems side by side. (Illustrative scenario - not a measured result.)

Frequently asked questions
How long should the parallel-run period last?+
Long enough to see at least one full reporting cycle in both systems - typically four to eight weeks - so seasonal or weekly patterns can be reconciled, not just a single snapshot day.
Can old historical data be imported into Amplitude directly?+
Depends on your source platform and data access - some historical data can be backfilled via API or file import, though not every source concept has a clean one-to-one match in Amplitude's schema. The migration scoping call identifies exactly what transfers and what needs a documented mapping decision instead.
