AutoUpgrade Automates Upgrade of a PDB via Unplug-Plug-Upgrade

AutoUpgrade automates unplugging a PDB from a CDB, plugging it into a higher version CDB, and upgrading the PDB to that new target version.

As part of the process to simplify upgrade, starting with Oracle Database 21c, you can upgrade pluggable databases (PDBs) using an unplug/plug, where the upgrade occurs when you plug the PDB into the target release container database (CDB). This feature adds another scenario in which AutoUpgrade can automate the entire database upgrade process.
