ReadyNas Duo to 212

Yes, but you are making it way to complicated.

1. Remove disk 1 from Duo
2. Format disk 1 in 212
3. Copy data from Duo disk 2 to 212 disk 1 via ethernet
4. Remove disk 1 from 212 and put aside5. Remove disk 2 from Duo6. Format disk 2 in 2127. Remove disk 2 from 2128. Insert disk 1 in 2129. Insert disk 2 in 212, format, and allow it to be added to the volume for RAID1.
The process will work regardless of which drive you move first. If this is a DuoV1, then moving drive 2 first may be the better solution because of the way OS4.1.x creates a RAID. I'm not as familiar with that as StephenB , who may want to add something here.
Note that you have no data redundancy during this entire process, so insuring your backup is up to date before proceeding is recommended. Of course, if you trust your backup sufficiently, then you could just move both drives to the 212, format and create a volume, and restore data from backup. But the process above maintains two copies of the data, counting the backup, where restore from backup does not.
When you move the second drive to the 212, do it with the power on so the OS does not get confused by the content on it at boot time. For additional insurance, you could "unformat" the drive using a PC to simply remove all partitions, but hot insertion is still the best method.
If you have no current backup, then perhaps you should coinsider buying two new drives for the 212 and relegating the Duo and its drives to backup duty.
