Have existing Server 2012R2 cluster with iSCSI storage, need to move to new Server 2019 cluster with FC storage.
Do I have it right that one could do any:
1) Downtime (VMs moved via LAN from old cluster storage to new)
2) Add new 2019 hosts to existing cluster & configure at least one 2019 host to have iSCSI & then do LM?
3) Add new 2019 hosts to existing cluster & configure at least one old 2012 R2 host to have FC & then do LM?
How well 2019 adds to 2012R2 cluster?
If 2 or 3 then after data move, remove 2012R2 hosts & upgrade cluster version?
Any other options?
