What Happens During an Upgrade Rollout
You can start the Prisma Access Agent upgrade process by clicking
Start from in Strata Cloud Manager. When the upgrade rollout begins, the end
users' devices will be upgraded according to the order of the rings they belong to.
Any devices that are offline or not reachable during the staged rollout are placed
in the default ring. Likewise, any new devices that connect to Prisma Access
after the stage rollout has completed, are placed in the default ring. After Rings 0
to 4 have been upgraded, the devices in the default ring will get upgraded in the
order of their assigned rings.
When a ring is active, the agent is upgraded on any device that belongs to the ring,
provided that the device has basic local network connectivity, can connect to the
service that manages the agents, and can authenticate with the Endpoint Manager.
Each ring will be active for 72 hours, after which the next ring will begin.
Devices that are in a disconnected state (with no tunnel connection established) can
be upgraded. Devices that are offline (not connected to the service that manages
agents) cannot be upgraded. When a device comes back online and if the rollout is
still active for the ring that the device belongs to, that device will be upgraded
as part of the ring. If the ring is no longer active, the device will be upgraded as
part of the default ring. This upgrade behavior applies to quarantined devices as
well.
The following table shows the duration for each stage of the ring upgrade cycle:
| Stage | Duration |
|
Agent rollout notification period
You are notified of the upcoming upgrade after clicking
Start. The upgrade begins
automatically at the end of the notification period.
| 5 minutes |
|
Active period for each ring
The runtime for each upgrade ring (Rings 0 to 4 and default
ring). Devices that missed the stage rollout are upgraded as
part of the default ring.
| 72 hours per ring |
If a failure occurs during a ring upgrade, you can
stop the staged rollout to troubleshoot and resolve any issues before
starting the rollout again.
