Swapping disk sets between units
Software version: 6.4.2
I have:
NASPro with 2 x 1TB drives
NASUltra with 2 x 2TB drives.
I would like to retain the data on both but move the Pro's 1TB drives to the Ultra and the Ultra's 2TB drives to the Pro.
I thought of these ways:
- - simply swapping the disks over keeping the disk order the same, or
- - Backing up /data, then swapping all the disks, reformatting and building the array. Then copying the backup /data folders over: Pro to Ultra, Ultra to Pro
I don't know what NAS specific data is on the drives, e.g. NAS specs, passwords or anything else
I am sure life isn't simple so would appreciate advice on the best way to achieve this.
Thanks,
David

(a) create the (empty) shares on the pro that will end up on the pro
(b) use the web-ui backup to transfer those shares from the ultra to the pro
(c) delete the "pro" shares on the ultra, and create the (empty) shares you want on the ultra.
(d) use the web-ui backup to transfer those shares from the pro to the ultra
(e) delete the extra shares on the pro.
This implies that the pro can hold all the shares from both machines. If not, you will need to either offload to external storage, or try to "shuffle" one at a time. That is for share A on the ultra, and share B on the pro:
(1) create share A on the pro
(2) copy share A to the pro
(3) delete A from the ultra
(4) create share B on the ultra
(5) copy share B to the ultra
(6) delete B from the pro
ad nauseum...
What happens to file/group owners depends on how the UIDs and GIDs are assigned. Ideally you'd have exactly the same users/groups configured on both machines - then rsync would preserve ownership and permissions. If that's not what you have now, then you might have some permissions/ownership cleanup you'll need to do at the end.

You should be able to simply power down, remove the disks (label order) and move the disks across keeping the order the same. Of course, it would be advisable to update your regular backup before attempting this if the systems are still working fine.
