Changing all disks on RN314

Personally I tend to run the disks until I see some signs of failing.  Though of course others will replace them on a schedule.

If I remove all old disks and plug the new two disks I imagine that I will lose also the partition with the OS6 and it will be reinstalled starting from scratch -something that I would like to avoid. 

Normally the process would be to replace the disks one at a time, and wait for the system to resync before moving on to the next.  But that would require you to replace all four.

The other way is to back up the files, power down the NAS and remove all four disks (labeling by slot).  Then put in the two new disks, and power on the NAS, doing a factory install.  Reconfigure the NAS (creating any user accounts, shares, installing any apps, etc), and restore the files from the backup.  OS-6 will be reinstalled from scratch (as you note in your post).  Is there a reason why this is a problem?

There's no way to shift from 4-disk XRAID to RAID-1 via the web ui.  There is a fairly risky way to do that with ssh/linux command line.
