Migration of MOVE AV to a new server in an existing environment prevents the service registration. All other requirements can be successfully met. But, until the existing MOVE service is unregistered and removed from server A, the new ePO server B can't be registered with the service manager for MOVE in NSX.

To use MOVE on a different ePO server where a disaster recovery is followed, a complete removal and unregistration is needed. You must then register and redeploy the MOVE appliances.

You see the errors below in the Orion.log if another ePO server is already registered with the Service Manager in NSX:
