I think you should be fine going to 3.00.03, but back up everything
and if it fails, installing 3.00.02 might help to identify the
problem by narrowing the search.

If you've not used git revision control, I think the best way is to
unpack the original 3.00.01 source, take a copy of your modified
3.00.01 source, do the upgrade and then use a "three-way merge with
ancestor" tool on the directories containing the modifications.  Emacs
has one called Ediff

but I expect other pretty ones are available.  Again, backup everything.

Hope that helps,
