Hi,

I've 2 virtual DHCP failover servers (2012) on 2 Windows Cluster nodes. One of the cluster nodes has an issue and I'm planning for a maintenance window with zero downtime. For zero downtime, my plan is to move those 2 failover DHCP server (VM) to another new physical server and run them from there, till I finish my maintenance and then return it back. Need an advice, how smoothly I can migrate these virtual DHCP failover servers? Will it work if I simply copy and paste these DHCP vhd's and create VM on another server and run?

TIA.
