Okay, unfortunately I'm back. I followed the procedure outlined above, but it doesn't appear to have worked quite right, in my case at least.
I added two additional drives from my old array (one old parity drive, the other containing data). They showed up on the new server as unattached storage. Actually, *all* the drives, old and new, initially appeared as unattached drives, but I was able to add the original three (one parity, 2 data) back into the array without any problem. But when I attempted to add either of the two "old" server drives to the array, I got the error, "You may not add new disk(s) and also remove existing disk(s)." I rebooted the server, but the error persisted. Finally, I read on another forum post that the error was because I needed to "... let the parity sync finish before adding new disks (or doing a new config), you cant add new disks while parity is not green." So, I left the parity to sync overnight and it finished without errors. However, when I try to add my data disk to the array, I get a warning that "all data on this device will be overwritten when the array is started."
So, I'm back to square one. I can't seem to find a way to add the old data disk from my old array into this new array without losing its data, even though I did a New Config on it beforehand.
Any advice on how to add the data disk, or do I have to resort to copying the data over? (If I have to do that, it's not the end of the world, just annoying and time-consuming, considering the data's already there.)
Thx.
