Another useful check is to build the package both before and after your
transition work, then compare the .deb contents of the two packages with
debdiff.  The first couple of times, you might have to closely inspect the
differences (e.g. in symlinks, etc.), but you'll pretty quickly get a feel for
the expected differences.
