After posting I realized I could just try this out in a VM; the following appeared to work fine on a small VM MBR disc with one FFS partition and some extra space fore and aft: $ gpt migrate -A wd0 It did throw an error message but still did the migration. Afterwards I editted /etc/fstab like so: $ sed -i 's/wd0a/dk0/' /etc/fstab Thanks for all the feedback. Regards, -B
