Two choices: 1) rename the datafiles while the database is mounted, but not open, using 'alter database rename datafile <old_name> to <new_name>' (check my syntax on that - going from memory). 2) Recreate your controlfile with the new filenames/locations (i.e. in a nomount stage, issue 'create controlfile blah blah blah'). The former is probably your best bet - less chance to screw something up.
