The Link Controller base license improperly prevents DNS namespace iRule commands.
An administrator cannot add DNS namespace commands to an iRule. Cannot upgrade from a pre-11.5 configuration, where the commands were working, to 11.5.4 through 12.1.2.
A Link Controller license without an add-on that allows Layer 7 iRule commands.
To enable upgrade, remove DNS namespace commands from the configuration prior to upgrade.
DNS namespace iRule commands are now properly accepted with a Link Controller base license.
