Always conduct upgrades in sequence: first the Microsegmentation Console, then all apoctl clients, then the enforcers (optional).
After upgrading the Microsegmentation Console, you should upgrade all apoctl clients.
Otherwise, you may experience unexpected behavior.
The upgrade of apoctl consists of a simple reinstall.
Never upgrade the enforcers without first upgrading the Microsegmentation Console.
Newer enforcers cannot communicate with older Microsegmentation Consoles.
Upgrading the enforcers is optional as older enforcers can continue to communicate with newer Microsegmentation Consoles.
Upgrading to 5.0 requires a one-time migration from network policies to network rulesets.
