------------------------------------
Resolution: Duplicate
> Document Ozone 2.2.2 upgrade prerequisites and Recon TLS checkpoint workaround
> ------------------------------------------------------------------------------
>
> Key: HDDS-17617
> URL: https://issues.apache.org/jira/browse/HDDS-17617
> Project: Apache Ozone
> Issue Type: Task
> Reporter: Wei-Chiu Chuang
> Priority: Major
> Labels: documentation, website
>
> Update the Ozone 2.2.2 release notes with release-specific upgrade guidance:
> * Back up metadata, configuration, and service credentials before upgrading.
> * Configure the OM, Datanode, Recon, and SCM service principals on every SCM.
> * Document the full SCM checkpoint download failure in Recon when security
> and gRPC TLS are enabled, and the conditional existing-database workaround
> using ozone.recon.scm.snapshot.enabled=false. Periodic container
> reconciliation remains enabled; manual full checkpoint downloads remain
> affected.
> * Clarify that this patch upgrade introduces no layout-version bump.
> Link to the existing upgrade and downgrade guide rather than duplicating its
> generic procedure. Limit the website change to the 2.2.2 release notes. The
> Recon behavior and workaround are based on released-source review and have
> not been validated by a live secure-cluster upgrade test.
> Related issue: HDDS-17235.
