Migration guide

How to migrate from Looker to Redash

Here the bad news is unavoidable: analytics history almost never migrates between different platforms, because each one measures and aggregates data differently.

1. 1

   Export a historical summary from Looker as a file

   First, export your key reports (monthly traffic, top sources, conversions) for the last 12-24 months to CSV/PDF as a reference file — it can't be recovered afterward.

2. 2

   Install Redash's script in parallel

   Add Redash's tracking script to your site without removing Looker's yet, so both measure in parallel for 2-4 weeks and you can validate the numbers make sense.

3. 3

   Recreate your goals and conversions

   Looker's custom conversion events don't migrate — set them up again in Redash using the same definition (e.g. form submission, purchase completed).

4. 4

   Remove the old script

   Once you confirm Redash is capturing traffic correctly, remove Looker's script from your site and keep only the exported historical file as reference.

These steps are a general guideline — the exact export menu can vary depending on Looker's plan and version.
