The image shows the topology of the use case described above.

In the upper left is the source primary CDB (CDB100) containing 3 PDBs (PDB001, PDB002, PDB003).

The lower left shows the standby CDB for CDB100 (CDB100_STBY) containing 3 PDBs (PDB001, PDB002, PDB003).

An arrow from source primary CDB CDB100 pointing to its standby CDB100_STBY is labeled "Data Guard Redo Ship/Apply".

The upper right of the image shows the empty destination primary CDB (CDB200) containing no PDBs.

The lower right shows the empty standby CDB for CDB200 (CDB200_STBY) containing no PDBs.

An arrow from the destination primary CDB CDB200 pointing to its standby CDB200_STBY is labeled "Data Guard Redo Ship/Apply".

Between the source primary CDB (CDB100) and the destination primary CDB (CDB200) is shown an ASM disk group with solid lines to each primary CDB. There is also an arrow labeled "Unplug/Plug via Broker Migrate No File Copy" between PDB001 in CDB100 and the destination position for PDB001 in CDB200, indicating that the PDB is in the process of unplugging from the source and being plugged into the destination.

Between the source standby CDB (CDB100_STBY) and the destination standby CDB (CDB200_STBY) is shown an ASM disk group with solid lines to each standby CDB. There is also an arrow labeled "Broker Migrate Create ASM Alias No File Copy" between PDB001 in CDB100_STBY and the destination position for PDB001 in CDB200_STBY, indicating that the PDB is in the process of unplugging from the source and being plugged into the destination.
