I have a 2019 HyperV Host without any replication and I need to run Windows update on the host and the VM server (also Server 2019) that resides on it - Is the safest process to :
- Take a Checkpoint (snapshot) of the VM (Windows Server 2019) then run update and reboot as needed?
- Once the VM is updated and proven it is in good shape, create a restore point on the Host,
- Shut down the running vm, so that it is unaffected by Windows updates and reboots of the host.
- Complete the updates and reboots on the HyperV host.
- Restart the Server VM and confirm is is running as expected?
I hope to establish replication eventually - possibly with a HyperV host to be established in either Oracle or Azure Cloud. For now I need to run Windows updates while minimizing the possibility of crashing / not recovering and maximizing a process for backing out if needed.
