Is GTM/DNS software version is the same as LTM OS version on the same physical machine?

Hi Herman2024 

Yes, in your case, both GTM/DNS and LTM modules are part of the same BIG-IP appliance running version 17.1.x.x. Therefore, by default, they share the same underlying BIG-IP version. It is not possible to upgrade the GTM/DNS independently of the LTM, as these modules rely on the same underlying software version.

Upgrading or downgrading any module requires a full upgrade or downgrade of the BIG-IP software, which affects all provisioned modules (GTM, LTM, AFM, etc.). If you need different versions for GTM/DNS and LTM, they would have to be on separate physical or virtual devices.

Hope you query resolved

Thanks
