Moving to git from svn

I am contemplating on switching to git from svn at our workplace. we have about 5 devs onshore and 10 off-shore. my main concern is that most folks are used to the rich UI of svn, where git is primarily a CL based tool. I can manage the on-shore devs but not sure how to get off-shore going. I am thinking of doing piece-meal type by moving one utility project to git and have folks warm up to it. or should I do a boot-camp and move everyone to git?
