I have 1 RAID6 (root) and 1 RAID1 (boot) array running across 7 drives
in my Ubuntu 20.04 system.  I bought a new motherboard and CPU that I'd
like to replace my current ones.  In non-raid systems, I get the sense
that it's not a very risky operation.  However, I suspect RAID makes it
more tricky.

Luckily with software RAID using mdadm it does not.

Wondering if anyone can offer any advice here?  Do I have to make sure sata
cables are plugged into corresponding ports in the new motherboard?

No, the order of cables is unimportant. Just plug everything in, and it should
work.

May have to check in BIOS that it doesn't require a UEFI boot partition, but
allows to boot from a legacy-style bootloader, in settings such as "Launch
CSM: Enabled" and "Boot device control: (UEFI and) Legacy".
