Ruby- it also occurred to me that MT can probably mark your old id as inactive (zombie/sleeper) which would make the transition more obvious to friends. This of course assumes you will not be using the old account ever again.

In my experience, if you are linked to Facebook the transition is easy. If not you may need to check carefully to see that MT transferred everything.
