Upgrade Keycloak version 18.0 to 25.0

[amir4895]

Hi all,
I’m trying to upgrade from v18 to 25 but that seems to be tricky.

when trying to do one step upgrade i saw some issue related to liquibase Upgrade liquibase version to avoid a bug where a changeset is execute… by vramik · Pull Request #23560 · keycloak/keycloak · GitHub

so i tried to do two hoop upgrade

18->21.1.2->25.0 but im always getting timeout in the migration part.

following this topic:

Keycloak Upgrade Docker Container From 18.0.2 to 21.0.2 With +200 Realms

Hi dear community, I am reaching out to you because we need some community help on upgrading our KC version from 18.0.2 to 21.0.2. We run a multi-tenancy approach where each organisation with users is represented by a realm. Since we serve multiple organisations, we have more than 300 on our KC. I am aware of the fact, that around 300 realms, KC suffers significant performances issues, and we do have a plan to move away from this approach, and go for groups. However, we decided first to upgrade …

i tried to prolong the timeout of QUARKUS since i got this in my logs

: org.hibernate.HibernateException: Transaction was rolled back in a different thread!

but it didn’t help

i also tried to do another hoop i.e. 18->19->21->25 but each hoop that include upgrade to 21 is also falling in the migration with the same errors

any idea anyone?

@amir4895 follow the initial discussion. See my reply. Did you find the quarkus.properties file in the keycloak conf folder? /opt/keycloak/conf?

Answer in the first discussion thread please.
