Switching analytics tools feels risky because the data is the product. Lose the history and you lose the ability to answer "is this better or worse than last quarter." So most teams stay on a tool they have outgrown, because leaving sounds like a bad week.
It does not have to be. A migration off PostHog can be boring, reversible, and done on your schedule. Here is the path we recommend.
First, decide why you are moving
Be specific, because the reason shapes the plan. Common ones:
- Cost at volume. Event-based pricing that scaled faster than your revenue.
- EU residency. A customer or a regulator now needs data to stay in the EU.
- Surface area. You wanted clean product analytics, not a platform to administer.
If none of these bite, stay. If one does, keep reading. We keep an honest, side-by-side breakdown on leatmap vs PostHog.
Run both in parallel
Do not cut over on day one. Add the leatmap SDK alongside your existing tracking and send events to both. This is the single most important step, and it is cheap:
- You keep PostHog running and untouched, so nothing is at risk.
- You start building history in leatmap from today, so the clock is already ticking when you are ready to switch.
- You get a live A/B of the two tools on identical traffic.
Reconcile the numbers before you trust them
Now compare. Pick the metrics you actually run on, sessions, signups, a key funnel, and check that leatmap and PostHog tell the same story. Where they differ, you usually learn something:
- Server-side dedup means a prefetch or a double-fire shows up once, not twice.
- Bot filtering at the collector removes traffic your old numbers were quietly counting.
The goal is not identical numbers. It is numbers you understand.
Cut over when you are ready, not before
Once the two agree (or you understand why they do not), flip the primary tool to leatmap and keep PostHog in read-only as an archive for as long as you like. There is no forced deletion and no big-bang weekend.
What you carry forward
The point of the parallel run is that by cut-over day you already have weeks or months of leatmap history, clean and EU-resident, captured while PostHog kept the lights on. You did not lose your data. You replaced the pipe without draining the tank.
Start a free workspace and dual-send today. The history you build now is the history you keep. See the full comparison on leatmap vs PostHog or the pricing page.
