Hyper-V Do I need to start backups from scratch when moving to Failover Cluster?

[WMUDLeV]

I'm beginning the move from VMWare to Hyper-V. In order to get the hardware evacuated while keeping everything up, I need to stage everything. I'm going to start moving some non essential VMs for testing over to an empty server I have, that will free up resources on one of the two "Cluster" servers which will become Hyper-V host 2. I will then migrate the remaining machines from the other "cluster" server over to HV2 leaving me with a third empty machine to become HV3. Once that is done I'm free to reformat our SAN for Failover Cluster shared volumes.

My question is in the interim while I'm moving these VMs to standalone servers, I will be backing them up with Veeam. Once everything settles, all VMs will be in a Failover Cluster with shared storage. Will I have to start from fresh backups all over again, or will Veeam recognize that these VMs are the same VMs that were being backed up already?

Followup Question, 1 of the 3 servers will be at another location as a standalone Hyper-V server, not part of the Failover Cluster. I would like to replicate VMs from the failover cluster over to this server as disaster recovery. Is that supported?

TIA
