Hello,
we have an old 2008 R2 H-V cluster with data on CSVs (on iSCSI SAN) and we need to move them to 2012 R2 cluster.
I'm aware of other migration paths and supported/unsupported scenarios, but my question is this - will the following work (without any data loss)?:
a) shutdown all VMs in 2008 R2 cluster
b) remove CSVs (remove from CSV, remove disks from FCM)
c) disconnect and unpresent the LUNs from 2008 R2 cluster
d) present & connect the LUNs to the 2012 R2 cluster
e) add the disks to cluster and to CSV in the 2012 R2 cluster
f) import the VMs & start them
