Is downgrade from 17.0.1 to 16.1.0 supported?

[Mateusz Kruszyk]

Hello everybody.

I am testing downgrade procedure for Keycloak. I have two scenarios.

First one: 

1) Install 16.1.0

2) Upgrade to 17.0.1

3) Downgrade to 16.1.0

works fine. However second one :

1) Install 17.0.1

2) Downgrade to 16.1.0 

fails. Is that a valid scenario at all? 

thanks

Mateusz

Hi Mateusz,

 

in general, you cannot downgrade as there is now way to roll back a database migration. You could only restore a backup – but then you would lose all changes that happened after the backup. Only exception to this is if there are actually no db migrations in a newer Keycloak version.

 

Best regards,

Sebastian
