The motherboard on which I was running a mdadm 8TB array comprised of
5 x 2TB drives has packed up so the array needs to be moved to a new
motherboard.

Is the sequence of connectivity to motherboard SATA ports important or
does mdadm identify each drive and automagically know its sequence in
the array?

The array position is stored in the array metadata on each disk, so the
physical connection order does not matter. If you're using a RAID1 array
for the boot drive, you'll need to make sure that the correct disk is
set in the BIOS to boot from though (or that the boot block was
installed to all array members).
