If you are quite studious, you can get a rolled back Entity back into a 'clean' state so that you can successfully merge them back into a persistence context (you'll need to clear out _pcVersionInit, version fields, auto generated Id fields, and the StateManager field)... but the easiest path might be to copy all of the data over to fresh(newly created) Entities.
