Can you tell me how to force clients (3040, 3020, 3010 and c00x) to get the new dhcp tags? I am trying reboot, shutdown, decrease dhcp lease etc… but many clients keep the old config and do not upgrade.
Clients will only use the DHCP or DNS information to find the WMS once. After that, they will no longer use DHCP/DNS tags.
If you want them to use those tags again you would have to remove them from WMS or factory reset them.
Another way would be to define the new WMS tags in your WMS policy.
