Software upgrade and rollback

The Fabric Services System supports software upgrade from one release to a newer one in a KVM or VMware vSphere environment running in a supported configuration (with one deployer VM and one, three, or six Fabric Services System virtual machine nodes).

The procedures in this section describe how to prepare for the software upgrade and execute the software upgrade. The rollback procedure describes how to rollback after an upgrade, if needed.

The supported upgrade path is as follows:

Release 22.8.2 to Release 22.12.1

Note: In the software upgrade and rollback procedures, Release 22.8.x is referred to as the old release and Release 22.12.y is the new release.
