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:
22.8.1 to 22.8.x (where x > 1)
