In PPEM 2.2, packaged API commands can now be sent by the manager. Typically, these are API commands required for executing various operations.

If the manager and agents operate on different PPEM versions, you cannot create instances and perform any actions with databases and their objects, such as schemas.

To avoid backward compatibility issues, select the date and time when no operations with databases and their objects are scheduled, and then upgrade both the manager and agents to version 2.2.
