Note that you need GPT for UEFI boot disk.
This is only a requirement for Windows (and possibly broken UEFI
implementations). The UEFI specification allows to boot from a drive
with a DOS/MBR partition table. Else, assigning a DOS/MBR partition type
code for EFI system partition (0xef) would be pointless.

that /boot is a RAID1 array (how do you resize all the partitions, etc?).
Setting up redundant EFI boot with software RAID is a pain and a hack.
Resizing RAID partitions is a pain.
So I advise you keep legacy boot as long as you can (but prepare for EFI
boot on a test machine or VM).
