Disreguard the message about not combining places in TMG, it should have read UFT (senior moment).
DO NOT MERGE DUPLICATE PLACES IN UFT IF YOU HAVE MORE THAN ONE PROJECT.
If you want to do something with your places in TMG prior to transfering to TMG, make sure all of the duplicate places are alike. The short place names should all match and the modifier, city, county, state, and country places in the long place names should all match and be in the correct location.
When you get to TMG all you have to do is execute one command to combine all of the duplicate places automatically.
