The core structure and layout of a git repository hasn't changed since may 2005, so it should work just fine provided you use any git version that actually has a version number.

We've upgraded in a hodge-podge fashion at $dayjob. One of our servers is still running 1.4.something. We've never even come close to anything resembling a problem. It's actually a bit weird, since we started using git in late 2005 and it's so far been the most reliable and backwards-compatible piece of software we have in the company pretty much ever since.

Since you have such high demands on problem-free migration, I suggest setting up a repo server running the new git (on the server side) and having some people test against the new git with both old and new git, as well as testing new git against the old servers.

Just get a backup first. I'm 99.9999999999999% sure you won't need it because of anything git does, but better safe than sorry, eh?

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
