That simple answer is:

  1. Copy or rename the datafile at the O/S level BEFORE attempting to rename it in the database. Take the tablespace offline, copy the datafile to the proper name, rename the datafile in the database, recover the tablespace and then bring the tablespace online. You should then be able to drop the old datafile at the O/S level. 'Renaming' the datafile in the database merely updates the data dictionary, it does NOT rename files at the O/S level.
