Hi David and all, I used cvs2git, part of the cvs2svn package. The migration was made a bit trickier by the fact that I didn't have rsync access to the repo, so I had to use cvsclone to retrieve a coppy first. I've attached my migration notes to this email.
I am not too familiar with the packaging side at all; one thing we could consider as we do this Git migration is hosting PG on MELPA; this seems to work well for my company-coq plugin (https://github.com/cpitclaudel/company-coq/). The idea is that an emacs package (installable via `package-install-file`) gets auto-generated from the git repo every few hours, and gets hosted on MELPA, a third-party package archive. This makes installation of PG essentially platform independent, and makes it easier to deploy updates and bugfixes. An added benefit is that it allows other emacs plugins to register a dependency on ProofGeneral, so that installing them automatically installs PG as well. Clément.
