• A.Perform a clean shutdown of source database, transfer the files, create a destination PDB and execute noncdb_to_pdb. sql in the destination CDB
• B.Invoke DBMS_PDB.DESCRIBE in the source, create a destination PDB, execute noncdb_to_pdb.sql on the destination, and open the destination PDB.
• C.Invoke DBMS_PDB. DESCRIBE in the source , transfer XML files and datafiles, create a destination PDB, execute noncdbto_pdb.sql in the destination, open the destination PDB and invoke dbupgrade.
• D.Invoke DBMS_PDB.DESCRIBE in the destination , transfer XML and data files, create a destination PDB, execute noncdb_to_pdb. sql in the source, open the destinatipn PDB and invoke dbupgrade.
