Under certain conditions, nodes (or any other object with an IP address) in a partition that belong to route domain 0 will be treated as part of the default route domain for the partition after an upgrade.
Those objects might no longer be addressable or able to connect.
All of these conditions must be true: - A system is being upgraded from any TMOS v10.x release to any TMOS v11.x release after 11.1 or any TMOS v12.x release. Upgrading to 11.0.0 or 11.1.0 is not affected, but the upgrade process resets the partition's default-route-domain setting to 0. - It has a partition that has its default route domain set to a nonzero route domain. - That partition contains nodes with no route domain set (so the default is used). - That partition contains other nodes in route domain 0.
Set the partition's default route domain ID to 0 before upgrading, then set it back to its previous value after the upgrade. This field is only used by the GUI and shell, so temporarily changing it to 0 will have no effect on the dataplane.
