How to Override windchill part

Hi

Can anybody please let me know is there any way to override the new version of windchill part with the old one.

exa. I have created the  ABC ASM in windchill and its version is 1.2, now i made some structure change in it and its version became 1.3, later i thought old version is correct, is it possible to go back to old version by overriding the new one?

Thanks
