We have to switch heads from a FAS2050 to a FAS3140C. Currently the FAS2050 has five DS14mk4 fully populated, but its root volume is on its head.
Along with the FAS3140C, we bought two DS14mk4 to migrate the data from FAS2050 head's disks, since the FAS3140C doesn't have any disks itself.
The original plan was to copy the aggr0 from the old storage's head (alongside with the root volume) to the new storage, then make the new storage boot using the old storage's definitions, but evidently we are not completely sure how this could be done preserving the storage's metadata (e.g. LUN ownership).
Any ideas? Is the migration procedure attached close to what has to be performed??
PS: We have SnapMirror licenses for both heads, but no MultiStor.
