Replacing both disks in RAID1

I have a small server running FreeBSD 4.10, 2 x 80 GB drives mirrored on
Promise TX2 integrated RAID1 controller. I'd like to replace the 80 GB
drives with 200 GB drives.
Here's my current plan:
1. Attach one of the new drives to free ICH4 IDE port on motherboard,
partition it and transfer the data using dump/tar.
2. Remove the 80 GB drives, attach 200 GB drives (one with data, one
blank) to TX2 IDE ports and re-create the mirror using Promise onboard
3. Reboot, fix the fstab (if necessary) and be done with it.
I have one doubt with it. Currently my partitions are ar0s1a (/), ar0s1b
(swap), ar0s1e (/var) etc. When I create corresponding partitions on the
new drive while it is attached to ICH4 controller, the partitions are
created as ad0s1a, ad0s1b etc. When I then move this drive to TX2 port
and re-create the mirror the partitions should again be ar0s1a, ar0s1b
etc. Will it "just work" or will it not work at all?
Thanks in advance,
