Moving discs from a Duo v1 to an RN204
Hi everyone, I have a Duo V1 with a pair of 2TB discs. Sadly all is now full so I'm about to buy an RN204 plus an extra disc or two. This is where it gets fiddly though, becuase it seems that I can't...
You are on the right track. I just had to wipe my NV+ v2 (I have a Duo v1 also), it's a bit stressful wiping your main unit, but do the backup, check it carefully, then you are off. If you could host the 3TB soemwhere, then you could use that to backup your two 2TB (mirrored) drives. Then plug them in to a PC/Mac via USB to SATA adapter and delete the partitions. No need for low level format, deleting the partitions will effectively 'reset' the drives because all logical formatting will be gone. The new RN204 will simply format them (I've not done it as I mentioned, but I am pretty certain that will happen).
During my recent resetting of my NAS, I actually made two backups, as I reset my NV+ back to factory defaults clearing all data in the process. In fact, once you have backed up your old drives, inserting them in to the RN204 and performing a full factory reset should also blow away any current data and format (and avoiding the need to fiddle around deleting partitions). I am looking at getting a RN204 myself, but I don't have one yet.
I must emphasise, check your backups can be read in another machine, i.e. do the ful backup and check it can be ready on a PC/Mac independently. OK, I am paranoid about this, in my case backups all went fine with no issues at all.
Good luck. Come back with the results or if you run in to any issues. Folks here will be pleased to help out.
Hello richard-york,
Please see this article ReadyNAS: Migrating disks from RAIDiator 4.1 or RAIDiator 5.3 to ReadyNAS OS 6.
Please also note that each ReadyNAS model has its own compatibility list of HDD, so please check as well the HCL.
Welcome to the community!

Hi, this doesn't seem to be useful though I'm afraid, the closing comment is:
Note: The method to bring the data online inside the ReadyNAS OS 6 device only allows for the data to become accessible to be copied to an alternate location.
So this is all about data recovery if, say, the old chassis has died, rather than about migrating data and then moving over the discs.

The short answer is that you can't migrate the disks - if you want to reuse them the data will be wiped.
As aks points out, once you install a 3 TB drive in the new NAS you cannot add the old 2 TB drives to that array. You can use flexraid to create two RAID arrays (a jbod one for the 3TB drive and a RAID-1 for the 2 TB drives). The simplest thing to do is leave the duo running as a backup NAS (backing up some of the data on the RN204), and just get two 3 TB drives for the RN204.
