Upgrade worked like a charm.
I noticed two things.
When I tried to edit a term I couldn't save it, said that the term already exisits.
In my glossary terms I sometimes have a link to a picture in the form of [ url=][ img][ /img][ /url]. When this term is present in a post, the crosslinking popup shows horizontal and vertical scroll bars. Terms that are pure text show up just fine
EDIT: I also noticed that not all the terms are showing up.
