If the class names remain the same and they reside in the same classlibrary then simply using the new version of classlibrary (backup all your project first) should work.

If the class names have changed or the name of the classlib has changed then you have a headache of repointing the classes to new ones. I usually do it manually by hacking forms/classlibs, but AFAIK there is a tool available (if my memory serves me right by Glenn Domeracki (sorry for the last name misspell if any))
