KB86462 Unable to upgrade HCX Connector or Cloud Manager after reverting a snapshot
Impact/Risks:
After restoring a backup, all content that has a dependency on the vCenter inventory will not be accessible through the HCX standalone UI nor the vCenter plug-in therefore no migration or configuration workflows can be performed.
Network Extension services will remain active but no configuration changes can be done.
