Migration of existing disks to a new NAS box

My NAS RN21200 was replaced under warranty. I have 2 x 6TB disks which are mirrored and contain important data. When I received my new NAS replacement the documentation indicated that any disks inserted into it would be formated losing all data. However, I also have an article from Netgear 'ReadyNAS OS 6: Migrating a volume' which says to just put the disks in and the data will be accessible as per normal.

I am concerned that I get 2 opposing ideas from Netgear and at this stage I await clarification on what to do.

I would appreciate any feedback on this.

Hi Blacktimor,

If the replacement unit is just of the same model, you can just insert the disks in the same order on that unit. No data should be lost when you do that.

  Hi, the only problem is that I do not know the order of removal of the disks. So there is a 50% chance of getting it right and 50% chance of getting it wrong. What happens if I insert them in the wrong order?

    Hi Blacktimor, you wrote "the only problem is that I do not know the order of removal of the disks."
    
    Should you still have a logfile you downloaded from of the old box you could look into disk_info.log to see which disk was in which bay. You would see that by comparing the serial number on each disk with that what is listed in the logfile.
    
    Kind regards
