Thanks for info, it will be so.

Now, on boxes I am using it takes about 6 hours to do whole conversion and I cannot do it incrementally.

It would be great if we arrange few tests and then turn CVS read-only and switch to using Git. I will push current CVS converted to github in few minutes.

Some files show wrong version in HEAD. git cvsimport depends on old version of cvsps, and those cvsps people probably released newer version for some reason(s)… As long as I don’t want to dive into cvsps / git cvsimport source codes, no solution there. And I really do not have that kind of interest and/or time.
>> Ok, no incremental… This is where I tried cvs2git. It works well but it does not map authors (svn2git does, but although cvs2git comes from same team, features are not in concert). There is some arcane way proposed, but I lost trust when I saw svn2git from same team supports authors file, but cvs2git does not. Not big issue, but I had that in first try so I tried third way.

>> One proposal there is to not convert whole repository history. My idea is to convert from just before 5.8.6 was released (July 2010). Does anybody have something against this? I will still keep original CVS repo, and SVN conversion results (where all history is accessible). If there is oposition, I will spend some more CPU time and make full history available through Git. There are around 10000 svn revisions before July 2010, and total of 12752 as of today.
