thanks Dario for prompt response.

 

Presently i'm planning to upgrade only on one side.. say location B. So can i have GTM running different version on Location A :

 

vCMP Guest (GTM ) can remain on BIG-IP 12.1.2 on Location A but big3d_install will be performed (from Location B GTM) to install latest big3d version on this guest(Location A) and Host still will be in 12.1.2 version..will it work ?

 

please see the diagram i have attached:

 

Is there any best possible way, where i can upgrade only one side of DC (location) and rest location at later time probably a week later..

    Hello Rajneesh.

     

    As the documentation states:

    "BIG-IP DNS synchronization group communication

    Sync group members should run the same big3d version."

     

    So you can only have a GTM sync-group where all devices are running the same big3d versión. If both DC are going to have different firmware version, you should upgrade the big3d in the site with the lowest firmware.

     

    Please, don't forget to mark one of my answers as the best to help me for the contribution.

     

    Regards,

    Dario.
