Seeking Perl Knowledge/best practices for what I think is a pretty standard situation. We are attempting to upgrade the production version of Perl on several servers, using perlbrew. Perlbrew is working fantastic but we also need to make sure we get all of our CPAN module dependencies installed on the new installation of Perl. We do not currently maintain a list of module dependencies for our Perl apps, so we need a good way of making sure that everything makes it over into the new version of Perl. We tried the CPAN autobundle approach and it worked mostly, but seems to be failing consistently on 2-5% of the modules in the autobundle Snapshot file. Not sure if these files are actually used or not; we could invest a lot more man-hours into getting these modules to install but figured it would first be best to consult the Perl community. The core question is what's the best way to get an existing library of CPAN modules over into a new Perl installation and/or new machine entirely? Is there a tool that makes this a little less painful or are we relegated to CPAN install/troubleshoot migration cycle?
