What it actually takes
Step by step
A safe cutover plan
- 1
Audit
Inventory every workspace, project, or asset in Google Analytics you actually use. Most teams discover 30-40% is dormant.
- 2
Export
Run Google Analytics's official export. Note exactly which fields, relations, or attachments lose fidelity — those are your manual rebuild.
- 3
Rebuild structure in PostHog
Set up PostHog skeleton (workspaces, teams, permissions) before importing. Importing into an empty workspace creates a mess.
- 4
Import cleanest layer first
Bring in the data that maps 1:1. Defer custom fields, automations, and integrations.
- 5
Parallel run for 1-2 weeks
Keep Google Analytics read-only. Anything you find missing in PostHog, fix during this window.
- 6
Cut over integrations
Switch every webhook, Zap, link, and bookmark. This is the longest part — budget for it.
- 7
Archive, don't delete
Keep Google Analytics archived for 90 days. You will need it.
