Veeam Replication/Guest VMs OS patching

[rmcdonald75]

I am trying to do the following and want to make sure I am following the correct steps.

Critical servers that need to stay up and running so replication jobs are running for them. I need to patch the OS on these servers. Is the best way to do this is start up the replicas to a different network on my DR site and then patch the VMs on the PROD site. Once patching is completed undo the failover to PROD site?

If there is another way to do this please let me know as well.

Thanks
