I'm working on a project that used to use a proprietary CM system (aka oldCM).   At a point in time, the state of the code was frozen and used as the basis for commits in SVN.

What I would like to to do is take the individal commits from the oldCM and place them into git knowing that the time/date stamps won't match. Then I want to do whatever is necessary to setup git so that I can run "svn rebase" to pull in the commits from the SVN repository.

What is the easy way to do this?

There may be other tools that make this easier, but if I had this problem I would simply create two repositories, one for oldCM and one for SVN. I would then merge the two together (as branches with different roots) and do my rebase from there.

I haven't tried this, and maybe there is something I am missing, but there shouldn't be too much pain going that way.

Re: merging commit history

I did as Andrew suggested and created two git repositories  with one  branch using oldCM history and the second branch using having the svn history.  
Then I checked out the svn branch and rebased onto oldCM.   The head of the combined branch is named master.
How do I manually set git/git-svn up so that HEAD  points to -r rev  in the svn repository?    Googling doesn't come up with a solution; I previously thought google knows all.
When done, I would like git svn dcommit to be able to commit to the svn repo.

Thanks sps
