Three options (about migration):
- left things as they are and become incompatible without changing versions
- if you don't care about backward compatibility, just add +1 to all the
version fields and you are done.
- add this fields only for the new version.
IMHO 1st one is the worse option. I will go with the middle one (as far
as I know, nobody on arm uses interversion migration (as far as I know,
nobody uses migration at all).
If you (or anybody else does), a pointer to one setup that is known to
work is welcome.
Later, Juan.
