Limitations and Caveats in Release 3.1.5

If you wish to change the region on an already tagged interface in Prisma SD-WAN interface where the Service Links are established:
Remove the tag from the appropriate interface on Prisma SD-WAN controller and save the port.
Confirm that the service links created on Prisma SD-WAN controller are removed and the corresponding configuration on Panorama is cleared. This may take up to 5 minutes.
Tag the interface again with the updated region tag where you wish to establish the tunnel.

When migrating from CloudBlade version 3.1.1 to version 3.1.5 in Non-Aggregate Licensing mode in Prisma Access, tunnels may be rebuilt on sites that use ECMP tagging. The 3.1.5 CloudBlade version now considers all available ports for tunnel formation, rather than just the tagged ones. In such scenarios, you could experience some downtime for such sites. It is recommended to enable the
dry run
option to identify possible changes during migration to 3.1.5.
