ASM Directory or Alias Rename

I am on Oracle 10.2.0.4. I am migrating databases and consolidating servers. Unfortunately I have Databases that have the same name. The issue is that I now need to do a database rename.

I am thinking and have tried several approaches but wanted to get the feedback of the group for the best way to do what I am trying to do.

ISSUE: I have a database with the name testdb. In ASM I have everything under +DATA/testdb.

I rename the Database with db new id 'nid target=/ DB_NAME=testdb1 SETNAME=yes' -- This is because I just need a new DB name and not a new DBID. This is so the names don't clash under ASM.

Upon opening the DB, I now had a '+DATA/testdb' and '+DATA/testdb1'. All the files are created under the new location but the old ones are kept under the old. I went ahead and shut the DB down and removed all files under the new location (mainly just archivelogs). I then tried to rename the alias and directory. Both error out.

SQL> alter diskgroup DATA rename directory '+DATA/testdb' to '+DATA/testdb1'; alter diskgroup DATA rename directory '+DATA/testdb' to '+DATA/testdb1'
*

ERROR at line 1:
ORA-15032: not all alterations performed ORA-15177: cannot operate on system aliases

SQL> alter diskgroup DATA rename alias '+DATA/testdb' to '+DATA/testdb1'; alter diskgroup DATA rename alias '+DATA/testdb' to '+DATA/testdb1'
*

ERROR at line 1:
ORA-15032: not all alterations performed ORA-15113: alias name 'TESTDB' refers to a directory

One last option I am thinking of is using RMAN to copy everything over but instead I figured it would be a good idea to check with the group to see what ideas they might come up with, so here I am : )

Thanks,

Tom
