Move PDB to a Different ASM Disk Group

This post shows the steps for moving PDB related data files from one disk group to another. Currently the PDB data files reside in a disk group called +DATA and data file path is
+DATA/TESTCDB/9CBA2DF91A8C7012E053F4071FAC36E9/
TESTCDB is the CDB name and 9CBA2DF91A8C7012E053F4071FAC36E9 is the PDBs GUID.
The PDB will be moved to a ASM disk group called PDBDG.
1. Run a RMAN backup as copy to create data files copies in the destination diskgroup.
RMAN>backup as copy pluggable database testpdb2 format '+pdbdg';

2. As system tablespaces are also moved the switch to new location cannot be done while PDB is open.

So the PDB must be closed (downtime) and then switch to the data file copies.
