Legacy boot on GPT has some requirements, but it works

So what ? Aren't you going to create a GPT partition table on your
4-TB drives ? Else you won't be able to use the space beyond 2 TiB. (*)
A GPT partition table supports up to 128 partitions by default.
i won't have a choice as it looks like and so the easiest choice would
be migrate /boot completly to a USB-stick and simply ignore the current
/boot RAID1 which is just 482M small
I don't see how it is easier. Also, USB sticks are not reliable.
However you are right that you can get rid of the current /boot array; I
don't see the need for a separate /boot, its contents could be included
in the root filesystem.
since finally the new machines in the next step only support UEFI and
the uefi-system partition can't live on a RAID it would end there over
time anyways
Software is not natively supported by EFI boot but there are a few
tricks to set up a redundant EFI boot: create independent EFI partitions
on each disk, or create a RAID 1 array with metadata 1.0 (at the end of
the partition) so that the UEFI firmware can see each RAID partition as
a normal EFI partition with a FAT filesystem.
so for now my last remaining question is "how would the command look for
"Then with just two drives you change the raid to raid-1"
I would not convert existing arrays. Rather create new arrays on the new
disks and copy the data.
