As per Aruba’s 8.5.x doc:

Important Note: If you are upgrading 72xx controller from 8.4.0.x to 8.5.0.0, you will potentially run in to bug AOS-153899 which may not initialize Deep Packet Inspection (DPI) capability.
This can impact controller’s ability to identify application traffic and could affect firewall rules that rely on application signatures.
In order to mitigate the issue, you will require an additional controller reboot after the device comes up on 8.5.0.0.
Please review 8.5.0.0 release notes for additional information regarding bug AOS-153899 and necessary steps to resolve this issue. Please contact Aruba TAC for additional details


Once the controllers are back online and verified working as expected, you have two options. 1. Leave one partition running 8.4.x and 8.5.x OR 2. upgrade both partitions to 8.5.


OR


Verify that both mobility masters were upgraded. All other managed devices should still be running 8.4.x code.
