Moving database to different directory structure

Question

HI folks,
I have a production DB on a production server and a copy of that as test DB on test server. In both DB all data files are in the same directory.
It was asked me to make a copy of production DB into test DB.
Both DBs are already created, but because of sotrage space problems, I will have to move data files to 2 distinct partitions on test server. What I wanna do is:
1 - stop production DB
2 - stop test DB
3 - copy production DB data files(that are all on the same directory) to test server. On this test server data files will be placed on two different partitions
4 - start production DB
5 - start test DB
The question is, what happens to files that are moved to different partitions? what should I do to make oracle starts without errors?
I do not want to use import/export because the DB is about 20GB and it would take too much time to use export/import.
Thank you in advance.
Alex

what happens to files that are moved to different partitions?After moving files to test machine, you can do the following (on test machine) :
1. SQL> startup mount
2. See original file paths by
SQL> select name from v$datafile;
3. for datafiles in different partitions :
SQL> alter database rename file '<original path>' to '<new path>';
4. SQL> alter database open;
