Unplug / plug:and plug in to the new CDB:
Moving between CDBs is a simple case
of moving a PDBs metadata
An unplugged PDB carries with it lineage,

Advantages of Multitenant ArchitectureReduced CapEx & OpEx, Increased Agility, Easy Adoption
Self-contained PDB for each application Applications run unchanged
Rapid provisioning (via clones)
Portability (via pluggability)
Shared memory and background processes More applications per server
Common operations performed at CDB level Manage many as one (upgrade, HA, backup)
Granular control when appropriate
