This illustration shows a CDB with a CDB$ROOT container, a PDB$SEED container plugged into the root, and several PDBs plugged into the root. One PDB is a new PDB. The illustration shows the non-CDB being moved into the new PDB using the DBMS_PDB.DESCRIBE procedure. The illustration shows this procedure extracting an XML metadata file that contains information about the non-CDB's database files. A CREATE PLUGGABLE DATABASE ... USING statement uses these XML metadata file and the database files to create the new PDB.
