Known limitations

• The unit action resume-upgrade randomly raises a harmless error message: terminated.
• The charm sysbench may crash during a PostgreSQL charm refresh.
• Make sure that cluster-cluster replication is requested for the same charm/workload revisions. An automated check is planned.
• Contact us to schedule a cluster-cluster replication upgrade with you.

Requirements

The minimum Juju version required to reliably operate all features in this release is v3.4.5.

See the system requirements for more details about Juju versions and other software and hardware prerequisites.
