Migrate RAID5 with volume encryption from TS-453A to TS-453D

Hi,
I have a TS-453A (running QTS 4.4.2) with 4 WD-HDDs configured in RAID-5 and hardware-encryption switched on.
I have configured the RAID-5 as a storage pool with a thick volume and snapshots turned on.

Planning to move over to a more powerful TS-453D I'm wondering about the migration options:
According to this article https://www.qnap.com/en/how-to/knowledg ... he-old-one, everything should work including apps and setup; is that really true for encrypted volumes also?

As I'm "spoiled" by Windows I tend to think it could be useful not to just move disks from one machine to a new one but it could be an advantage (performance-wise??) to setup everything from scratch and then do a restore of data.
Does that make sense for a Linux-based NAS?

Thanks for your recommendations.

you should be able to just move the disks over

have external backups in any case

Backing up the complete volumes is tedious but necessary, thats clear.
Regarding snapshots: when moving over the volumes to a new device, I assume that also the old snapshots will be available? This would be nice.

Regarding setting up the new NAS from scratch and restoring data from a backup: is there any use (spacewise, performancewise) of doing this or does it just take much time and effort?

dont know about snapshots..I'd say they should move over

and a resetup shouldn't be needed in this case
