re-assigning volumes between storage pools

First, my environment is TSM 3.7.3.8 on AIX 4.3.3 running on a 3466 (rs/6000 
H50), using SSA disk.

We are starting to see one of our disk pools running out of room before the 
nightly process is complete.  We have 3 different disk pools defined, one for 
standard data, one for Oracle redo logs, and one for Groupwise data.  Lately 
the Groupwise disk pool (MAILDISK) has tripped it's 85% mig threshold before we 
complete the backups.  Our Oracle log disk pool (ORADISKLOGS) has room to 
spare.  I would like to reassign the 9.5gb volume (/bfaa1dk10/bf) to the 
MAILDISK pool.  Can someone please verify that the following sequence is 
correct, and also let me know if there is any reason not to use the volume I've 
noted:

1. upd vol /bfaa1dk10/bf access=readonly
2. move data /bfaa1dk10/bf     (wait for completion)
3. del vol /bfaa1dk10/bf
4. def vol maildisk /bfaa1dk10/bf
5. upd vol /bfaa1dk10/bf access=readwrite

Here is our current setup:

Volume Name               Storage      Device      Estimated    Pct   Volume 
                          Pool Name    Class Name   Capacity   Util   Status 
                                                        (MB)
