In theory, going from the tip of stable/10 to releng/11.0  should work as
lots of people did that back when 11.0 was new... from there you can follow
dim's instructions to get to the tip of stable/11 and from there to 12.2 or
stable/12. I have not tried that lately as I've retired even my old 10.x
testing jails some tie ago.
