[llvm-dev] Git Transition status?

[Gwynne Raskind via llvm-dev]

I had a similar experience when I did the same migration for PHP's repos in 2009. It took several months of prep and a multi-thousand-line script around cvs2svn, and they still lost some history in the process.

I don't know of any plus sides, aside from they weren't on CVS anymore ^^;

It's safe to say there will always be some rough edges when dealing with so much history.

For one example, clang.git doesn't actually go back to the first commit of clang, because weird stuff happened early in the svn history that threw off git-svn.
