I have initialized a SnapMirror XDP relationship (Ontap 9.3P11 at DEST, 9.1P16 at SOURCE) and broken the relationship in order to copy (robocopy) ALL data from the LUNs within the volume to a new NAS volume for CIFS - so I'm migrating from LUNs to CIFS here.
The copy process is about to complete so I intend to resync the mirror, update, break and run robocopy to sync to copy.
Is this is valid procedure or am I missing somehting critical here?
Additional info:
There are 7 LUNs in the volume which provide 11 VMDKs to a single Windows Server that are spanned as a single 100TB disk. So I am emptying that bad design into a NAS CIFS share via a FlexGroup volume for future growth.
