Dataplane Upgrade Overview

Dataplane Upgrade Overview

• An email notification from the Prisma Access app arrives 21 days before the scheduled dataplane upgrade start date. This email notification provides the dataplane upgrade start date for phase #1.
• In the email, you are asked to select and submit the location or locations to upgrade first and the preferred time window for the upgrade via the Prisma Access App.
  You can change and submit the first locations to upgrade and time window multiple times for a given tenant. The last submission that occurred seven days before the scheduled start date will be chosen by the service for the upgrade. You will not be able to make any changes within seven days of the upgrade start date.
  If you make changes, it might take up to 30 minutes for the changes you made to be displayed in the Upgrade Dashboard on Insights. You will be notified via email alert when the Prisma Access has processed and completed the changes.
  Palo Alto Networks strongly suggests that you select locations that reflect your entire deployment. For example, if you have a mobile user, service connection, and remote network deployment, select a location or locations that have all deployment types.
• Prisma Access will perform phase #1 of the upgrade on the selected location or locations within the local time window selected for those locations.
• If the selected upgrade locations have any combination of Mobile Users—GlobalProtect, Mobile Users—Explicit Proxy, Service Connections, or Remote Networks, the dataplane for each deployment will be upgraded to the required dataplane version, as described later in this section.
• Once the upgrade is complete in the first location, you’ll receive an email notification via the Prisma Access app. Palo Alto Networks recommends that you monitor the service for any new issues that occur immediately after the dataplane upgrade.
• In an unlikely occurrence where you see a new issue, report the issue to Palo Alto Networks technical support.
  The technical support team will investigate the issue and take corrective actions that may also include rolling back to the previous dataplane version. This decision will be communicated to you via the technical support case.
• If there are no new issues or a new issue is not upgrade-related, Prisma Access will proceed with the dataplane upgrade on the following weekend.
• The upgrade of the remaining locations will take place during the same time window you selected for the first upgrade (in local time).
• After the dataplane upgrade completes, you will be notified via email alert.

• Phase #1 upgrades the location or locations you chose on the first weekend using the time window you provided and notifies you via email when the upgrade is complete. If you did not choose the locations to upgrade first, or did not select a time window, Prisma Access makes the choices for you.
  Palo Alto Networks attempts to upgrade the locations during the four-hour window that you select via the Prisma Access app. However, completing the required upgrades during this window is best-effort and Palo Alto Networks cannot guarantee that the locations will be upgraded during that time. If the locations cannot be upgraded within the specified time window, you will receive an email notification. Palo Alto Networks recommends that you schedule a change request window starting at 8 p.m. local time on Friday and ending at 8 p.m. local time on Sunday for each of the two weekends when the dataplane upgrade occurs.
  Prisma Access makes the following changes to your deployment during Phase #1 of the upgrade.

  Deployment Type	What is Upgraded
  Mobile User Deployments	Prisma Access upgrades a single mobile user gateway, also known as the Mobile User Security Processing Node (MU-SPN), for the location or locations you specify.
  Remote Network Deployments	Prisma Access upgrades the backup (HA) remote network, also known as the Remote Network Security Processing Node (RN-SPN), then makes the backup remote network the active node for the location or locations you specify. The backup remote network connection is not upgraded until the following weekend, when the active and backup nodes are upgraded for all locations. If there are multiple RN-SPNs in the selected location, all primary nodes are upgraded to the new dataplane version.
  Service Connections	Prisma Access upgrades the backup (HA) service connection, also known as the Service Connection Corporate Access Node (SC-CAN), then makes the backup service connection the active node for the location or locations you specify. The backup service connection is not upgraded until the following weekend, when the active and backup nodes are upgraded for all locations. If there are multiple SC-CANs in the selected location, all backup nodes are upgraded to the new dataplane version.

  Between the first and second upgrades, monitor the first upgraded locations and perform connectivity, performance, routing, and logging testing to make sure that the locations upgraded successfully. If you encounter a service-impacting failure after the upgrade, open a Support Case with Palo Alto Networks Technical Support for assistance. Palo Alto Networks will attempt to resolve the issue by rolling back the dataplane to a previous dataplane version within 24 hours.
• Seven days after Prisma Access upgrades the first location, Prisma Access upgrades the remainder of your locations (Phase #2 upgrade), using the same time window you selected for the first phase, and notifies you via email when the upgrade is complete.
  The upgrade window can be longer. For example, if Phase #2 occurs during a national holiday in the United States of America, the second phase of the upgrade happens 14 days after the first phase instead of seven. The notifications you receive in the Prisma Access app show you the specific timeline for the upcoming dataplane upgrade.
