**Input:**

- Migration guide (generic) created by @mgarciaLKS as mentioned above: https://github.com/eclipse-tractusx/tutorial-resources/blob/keycloak-migration/migration-guides/GENERIC_BITNAMI_TO_CLOUDPIRATES_KEYCLOAK_MIGRATION_GUIDE.md

- Specific example of how it was performed for Industry Core Hub: https://github.com/eclipse-tractusx/industry-core-hub/blob/feature/keycloak-bitnami-to-cloudpirates-migration/docs/migration-guides/BITNAMI_TO_CLOUDPIRATES_KEYCLOAK_MIGRATION_GUIDE.md
- Upgrade target version suggested in migration guide is 26.x (latest at the moment is 26.5.x)

**Questions:**
- Okay to upgrade to 26.x ?
- Expected issues to consider when following the approach outlined in the migration guide?
- Portal IAM (CentralIdp, Sharedidp) currently using Bitnamilegacy keycloak:25.0.6-debian-12-r0 in last release and in version as deplyoed on INT. To be determined if this can be upgraded by Portal team.
- DTR still on Bitnamilegacy keycloak:22.0.3-debian-11-r14 on INT, as e.g. currently used by PURIS. DTR Helm Chart also references old versions.
- IRS: Has an old Keycloak reference in the "full-irs" chart, but according to feedback this was never used / is not a required component.

**10.04.2026 by @ds-hzimmer**
- BPDM successfully tested the migration guide for their "chart-tests" chart dependencies for Keycloak CentralIDP and PostgreSQL, using the linked guides. The guides were very helpful according to feedback, but Nico noticed issues for deploying multiple instances of databases (see "Upgrade of Postgres" task on board https://github.com/orgs/eclipse-tractusx/projects/61/views/1?pane=issue&itemId=133107482)
- DTR team contacted regarding updating the Keycloak used by their service with some open questions. Shared information regarding changes in token format between Keycloak versions 22.x and 26.x to consider.

DTR still open. Consider adding keycloak to TRG 5.07 (Do we still need that)?
