Removing Old HostedEngine Virtual Machine from Restored Self-Hosted Engine Environment and Enabling New HostedEngine Virtual Machine in the Manager.

Issue

• After restoring HostedEngine Virtual Machine (HE VM) from Restored Self-Hosted Engine Environment, the original HE VM shows up in the Admin Portal as Unmanaged VM and cannot be removed.
• This old machine is not in use anymore and needs to be removed from the setup.
• The new HE VM is up and running, but cannot be migrated between the HE hosts.
