I'm not sure, depends on how long ago you played.
Anyways, i've discovered what could potentially be a big issue.
If you've been using a ghetto massive smeltery for ore automation, all your lead is going to dissapear when you update, as it is industrialcraft 2 lead.. Perhaps you should give a warning before updating? Provide an oredictionary in the questbook?
You can craft that yourself. Its called "Forge Lexicon", with that you can change most items to their other ore dictionary versions.
There is also the MFR Unifier if you want to automate things. It works for both items and liquids.
