Moving a storage pool & volumes

[Lynx084]

Apologies for the long post...

I have 4 Disk Stations.
A 1813+ Currently my main file server and time capsule. It has 2 storage pools. One is 4 drives & the other 3 drives plus a hot spare.
A 1813+ Not working... hangs after running a while - might try a power supply replacement. It was the backup to the main server.
A 1019+ Currently the backup to the main server.
A 1512+ Recently new to me. Not in use yet.

After having a failure that Synology offers no help with repairing I am concerned with using the 1813+ as primary. Also, it would seem to make sense to have the newest Disk Server be the primary and the 1813+ be the backup server.
The second storage pool on the 1813+ is a time machine target for all my MacOS machines.

So, I have this shuffle in mind...
1) Move the 3 disk array (the time machine target) to the unused 1512+
2) Swap drives between the 1813+ and the 1019+

This results in 2 DS as primary storage and the 8 bay as the backup to both.

So, does this seem doable?

Can I simply take the 3 disks out of the 1813+ and put them in the 1512+, install DSM and do the migration?

Should I shut the 1813+ down first before removing the 3 disk array? It would seem prudent.

Sorry for the long post. I hope you could follow my convoluted story.

Thanks for any help.

Sounds good all in all. All “new” disk stations will have to be on the same dsm version before hitting them with migration but I see no problems with your plan of the bat.

Shutting down is ok but not mandatory considering those are hot swap models.

Thanks. I thought it might since just putting the disks from my failed unit in the new DS worked great.

All the units are at current DSM version (or were last week).

You are good to go then.
