Upgrades from pre-11.5.0 to 11.5.0 might fail to properly set the ha-group failover references in traffic-groups.
The ha-group failover method might no longer function.
This affects users of ha-groups who upgrade from pre-11.5.0 to 11.5.0. Upgrading from 10.x works correctly. The problem occurs because of the 11.5.0 ha-group functionality in which failover settings are configured per traffic-group. Previously, ha-group failover settings were configured per device.
None. To correct this issue when upgrading from pre-11.5.0 to 11.5.0, manually associate ha-group failover settings directly with traffic-groups.
The correct ha-group failover type is now correctly associated with the traffic-group.
In 11.5.0, ha-group failover settings are configured per traffic-group. In previous 11.x releases, ha-group settings were per device. When upgrading to 11.5.0, existing ha-group settings might need to be associated with traffic-groups manually. Without setting the traffic-group failover method, the ha-group score and failover cannot function. You can set the ha-group reference manually in the GUI or using tmsh commands.
