If you mean to move the disk containing ads1s1e from primary slave to the
primary master then the partition will automatically become ad0s1e.
But how are the other partitions in your system organised? Are you currently
using ad0s1a, ad0s1b etc.? These will move with the disk. If you are physically
swapping the disk connections these will become ad1s1a, ad1s1b etc. which will
be a problem. You'll need to fix /etc/fstab and arrange for a booting MBR on
the new disk and arrange for the boot sequence to find your / partition.
