I'd make a complete backup, zero the superblocks, and use --create --assume-clean to switch to v1.2 in place (with due care to maintain the device order and data offsets). (Save the output of "mdadm -E /dev/sdXX" for each member device before you start.) However, that fdisk can't understand the partition table shouldn't be hurting anything, so I wouldn't make it a priority. BTW, partition type 'fd' is deprecated along with v0.90 metadata, as it only impacts kernel non-initramfs autoassembly, and that only works with DOS partition tables and v0.90 metadata.
