I think there's supposed to be a migration assistant, but I've had very lack-luster results from it. I haven't tried it in a while, though... Last time I tried it, it could migrate a lot of core AutoCAD functionaltiy, but seemed to completely ignore all the C3D functionality. i haven't tried it in a while, though (since the 2010 release, I think...?) because the results were so disappointing. Not sure what may or may-not have been improved in the meantime.
You can always just upgrade your template to the latest release. There have been lots of bugs involved with this in recent years, though, the most-annoying of which are that some Expressions get broken when upgrading from 2010 and earier to 2011, or 2010 and earier to 2012, or 2011 to 2012. Very frustrating.
