it's doable. You will need to do a number of things before you can open the database, including recreating the controlfile (to change the sid) and renaming all the datafiles to new locations (so you don't overwrite the original database)

The easiest way (but not the shortest time) to do this would be to do a full database export, create the new database, with the SID you want and all the tablespaces with the new datafiles, import the full export with DESTROY=N and IGNORE=Y (this is VERY important!!!!! or you will overwrite the original datafiles).

you can also export every user individually and import them into the new database.... safest way but most time-consuming and biggest pain in the butt way to do it
