You do not need to update the BIG-IP software.

 

You can update big3d on the LTM by running it from the GTM (DNS) HERE is some more info on that topic.

 

Basically if you run it from the DNS to the LTM, if the DNS has a newer version, it will update the LTM to that version.

 

It shouldn't cause any issues with VIPs etc.

 

Hope that helps! If it does, please up-vote and select this answer, it would be greatly appreciated!

Yes, big3d versions need to be the same on all devices. That error seems to indicate that bigip_add didn't work properly.
