Going through all the different perldeltas or individual changelogs for each module over the last 16 years would still leave you with a lot of work to do so it's good you have tests. I strongly prefer tests that can expose incompatibilities between versions over the philosophical stance of a lot of Perl devs I've bumped into.

Both are in the CORE as of 5.38.2, but it's probably still too early to replace Class::MethodMaker with the new perlclass syntax. Test2::V0 is stable and feature complete enough to replace Test::More though. You also listed Date::Manip which shouldn't be causing you too much trouble; it's still under active development and works as advertised under 5.38.x.
