Is it possible to DECREASE the number of disks?
Hi, currently I have 5x2TB discs in the NAS (iOS 6.10.2). I'd like to move to 2x10TB configuration as the next step (and later add other 10TB ones as needed). Is this possible somehow? I do not want ...

Welcome to the Community!
It would be possible if you will use Flex-RAID and add 1 disk to your 6 Bay NAS and create a new volume (JBOD) transfer the data to that disk but we recommend doing a backup on another one to make sure you don't lose any in case of an incident and then remove your 5x2TB disks once all data has been transferred. You will have then 5 bays available so you can add the 2nd disk and then expand to RAID1.
It's not possible to just replace the disks since what will happen is that it will be part of the current RAID configuration (RAID5) so achieving the goal without creating another volume or without transferring the data to a new volume is not possible.
RAID configuration will also change from RAID5 to RAID1 since you will only use 2 disks in total.

Note any installed apps are stored on your current data volume. So you also need to uninstall the apps before you destroy that volume, and reinstall them afterwards.
FWIW, RAID isn't enough to keep your data safe, so you really should have a backup plan in place for the NAS. If you do make a backup as Marc_V recommends, I'd suggest that you might as well just do a fresh install with the new disks in place, and restore the data from the backup.

Thank you for the answers. I have X-RAID.
So most probably I'll keep the old 2TB discs and replate them iteratively as needed ... other options seem too complicated.
