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.
