For the PC version, yes, your saves will work fine with the UE. Just make sure that you save your characters folder when you uninstall regular DAO (and DO completely uninstall DAO) before installing the UE.
OK, so I just have to go find the Characters folder and pull it out or make a copy of it or something and I'm good? And thank you very much for the response.
The Characters folder is in Documents\\BioWare\\DragonAge\\Characters. When you uninstall the game it will give you the option to save those files or delete them as well. I generally make a back-up (copy it and save it elsewhere) just to be safe.
Another note: Any mods you may be using will need to be re-installed as well.
