I read the Git manual, FAQ, Git - SVN crash course, etc. and they all explain this and that, but nowhere can you find a simple instruction like:
SVN repository in: <
There is a new solution for smooth migration from Subversion to Git (or for using both simultaneously): SubGit.
I'm working on this project myself. We use SubGit in our repositories - some of my teammates use Git and some Subversion and so far it works very well.
To migrate from Subversion to Git with SubGit you need to run:
$ subgit install svn_repos
...
TRANSLATION SUCCESSFUL
After that you'll get Git repository in svn_repos/.git and may clone it, or just continue to use Subversion and this new Git repository together: SubGit will make sure that both are always kept in sync.
In case your Subversion repository contains multiple projects, then multiple Git repositories will be created in svn_repos/git directory. To customize translation before running it do the following:
$ subgit configure svn_repos
$ edit svn_repos/conf/subgit.conf (change mapping, add authors mapping, etc)
$ subgit install svn_repos
With SubGit you may migrate to pure Git (not git-svn) and start using it while still keeping Subversion as long as you need it (for your already configured build tools, for instance).
Hope this helps!
