Migrating to Quarkus 18.0.0 version

[sreekesh93]

We have 18..0.0 legacy keycloak currently if i am moving it to Quarkus version, is there any data migration happens?
We deployed quay.io/keycloak/keycloak:18.0.0-legacy on top of this we are migrating towards quay.io/keycloak/keycloak:18.0.0 which is the quarkus version of keycloak.
We could see all data created in legacy in quarkus, and to check backward compatibility we re-installed legacy version of keycloak which also works fine.

Question here is, Is data migration take place when we migrate keycloak from legacy to quarkus version?

Database used: Postgres

AFAIK there are no special migrations only for the Quarkus version.

Then I think there is a issue with this documentation, https://www.keycloak.org/docs/latest/upgrading/ here it stated that The database will no longer be compatible with the old server after the upgrade

This refers to a Keycloak version upgrade. Switching to Keycloak.X with the same version is not a version upgrade.

Yes we are migrating from legacy version (wildfly) to quarkus version of keycloak. So is the data migration expected in this case?

[sschu]

Not if you don't change versions, just switch between Wildfly and Keycloak.X with the same Keycloak version.
