thanks Dario for the information. I have already did vCMP HOST AND vCMP Guest (all LTM's) upgrade, I'm not looking for exact procedure, but i have doubt about the way i go for upgrade:

Step 1: Upgrade Location B

Option 1: I will upgrade vCMP Host on Location B DC and all vCMP Guest of Location B DC to 12.1.5.2

Step 2: on Location A

Option 2: GTM vCMP Guest 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 this is fine, or GTM sync group and iQuery will break and will lose sync with other GTM ?

Regards,

Rajneesh

Hello Rajneesh.

You have to upgrade everything besides the GTM and let the GTM devices for the last.

1) VCMP Hosts
2) VCMP Guests
3) VCMP Guests (GTMs)

The reason to do that is because as you mentioned before, to not break iQuery connection.
Check the next link:

Of course, you can avoid to let the GTM devices for the last step installing the proper versión of big3d.
