Consent Migration

Consent Migration is for websites moving from another CMP. It helps carry over clear previous choices when CleanCMP can safely read them.

What it does

On first CleanCMP load, the runtime can check supported previous CMP cookies. If a clear accepted choice is found, CleanCMP stores that as a normal CleanCMP consent record and skips showing a new banner.

Why it matters

Switching consent tools can create friction for returning visitors. Migration can reduce repeated prompts while keeping a new CleanCMP record of the migrated decision.

How to use it

Enable migration in Admin, choose the previous CMP format, publish, and test with a browser profile that has the old CMP cookie but no CleanCMP consent cookie.

What you get

Read previous CMP cookies
Create CleanCMP records
Avoid unnecessary re-prompts

Use Consent Migration in CleanCMP

CleanCMP includes this feature in the same workspace as the scanner, banner builder, Consent Mode v2 mapping, reporting, and publish history.
