Theres plenty of help on how to move /home, but they all involve moving /home to something line /home.old

I've got two software raids.

array1, which is RAID5 and currently has /home
array2, which is RAID1 and currently has /home-new

Rather than renaming anything, I was thinking of using the UUID to mount the array.

The steps would be to

1) boot into save mode
2) umount /home
3) umount /home-new
4) mount the RAID1 via UUID as /home and test
5) put changes in fstab (if everything works)

That way the RAID5 doesn't get touched at all.

Does anybody see a problem with this approach?
