3ware 9500s to 9550

I am currently running a 3ware 9550s 4 port on my WHS for the system disk -- two 500gb drives in a RAID 1 array -- these are the only drives on this card. Last night, one of the drives died, resulting in a degraded array running the OS on one drive. I RMA'd the damaged drive and awaiting a replacement, however I began to look for the much needed BBU unit for the 9500s. There is nothing available for less than $150, but I was able to find a 3ware 9550 4port card with the BBU for only $45.

My question is -- I can upgrade from the 9500 to the 9550 without having to format/re-install WHS? I think I would have to make a new RAID 1 array on the 9550 with two clean drives, pull one of those drives, clone my original drive to that, then hook it back up and let the card rebuild, resulting in a RAID 1 array with my original data mirrored. Any suggestions/ideas?
 
I think I've answered my own question -- found something in the 9590 user guide:

"After you have configured a unit on a 3ware 9000 series controller (9500S,
9550SX, or 9590SE), you can move it to a different 3ware 9000 series
controller, and retain the configuration on the new controller. This is referred
to as “array roaming.”

Sound about right?
