Upgrade to latest version of RAIDiator Do a config backup Remove both 1TB drives Install both 3TB drives Perform factory reset per instructions on link you provided above Restore Config backup * Can I then put one of the 1TB drives in bay 1 and let it sync to the new 3TB drive in bay 2 to restore the data? After it syncs, move the 3TB drive from bay 2 to bay 1, install the second new 3TB drive in bay 2 and let it sync? If ever that your RND2110 is a ReadyNAS Duo v1, I believe 3TB drives are not supported as per the HCL. Since I do not own a ReadyNAS Duo v1, I could say that it may or may not work. For vertical expansion, I would suggest to pull-out disk1 then insert the new drive then let it resync. After the resync process has completed, pull-out disk2 then insert the other new disk then let it resync again.

Thank you for the response Ixa. My ReadyNAS has been out of warranty for quite some time and I know the drives I purchased are not on the HCL. I'm hoping to also get feedback from StephenB who responded to my previous posts, to confirm I'm following the steps needed to include a factory reset so my new drives are formatted with 4k sector partitions; and to confirm my steps to restore/sync data are accurate.
