1. Check that all VMM servers are connected before you begin. 
2. Virtual machine replication will be paused and resumed during renewal.
3. Renewal might take a while. Ensure you don't have any recovery operations in progress or planned.
4. If certificate failures occur for new Hyper-V hosts that are added to the VMM server, retry the job 'Add or update host' on the Jobs tab.
5. If the operation fails, retry the Renew Certificate job on the Jobs tab.
