Upgrade Cisco VCS Control and Cisco VCS Expressway systems connected over a traversal zone
We recommend that Cisco VCS Control (traversal client) and Cisco VCS Expressway (traversal server) systems that are
connected over a traversal zone both run the same software version.

However, we do support a traversal zone link from one Cisco VCS system to another that is running the previous major
release of Cisco VCS. This means that you do not have to simultaneously upgrade your Cisco VCS Control and Cisco
VCS Expressway systems.
