Are you still using SVN but have some users clamoring to try out git? Kris.me.uk details all the commands and workflow to make it work. While I've known that git had some svn integration available, I prefered to switch cold-turkey to git. You can read the reasons I switched to git.
This article looks at not replacing subversion but continuing to use it as the master source repository and use one or more git mirrors to provide git for those that are familiar or wish to try it. Having subversion as the master repository can also alleviate management worries around authoritative sources, learning curves and any lost productive during upskilling, and other barriers to change. Those users using git can interact with both the subversion master and git mirrors, committing any work to be shared with all users back to subversion as and when appropriate.
