Additional notes
Guest & IoT Manager (GIM) does not support the traditional in-place BIN image upgrade that other Extreme Management Center appliances use. For each upgrade of GIM a fresh VMware OVA must be deployed to the hypervisor, configured for its base IP and DNS configuration, and via the GIM Administration GUI restore a prior backup configuration.

It is important prior to any XMC / Control / GIM upgrade that at least one configuration backup or automated backup is performed via GIM's Admin GUI Backup/Restore option.
If no manual or automated backup is performed and the parent XMC / Control deployments are upgraded to a new release before Guest & IoT Manager (GIM) then GIM may no longer be able to connect to Control. GIM will report "Incompatible XMC/NAC version" and this is an unrecoverable condition.
