4. Upgrade and restart the Expressway (

The web browser interface may timeout during the restart process, after the progress bar has reached the

The upgrade is now complete and all Expressway configuration should be as expected.
Upgrading Expressway-C and Expressway-E systems connected over a traversal zone
We recommend that Expressway-C (traversal client) and Expressway-E (traversal server) systems that are
connected over a traversal zone both run the same software version.

However, a traversal zone link to an Expressway system that is running the previous major release of
Expressway software is supported. This means that you do not have to upgrade your Expressway-C and
Expressway-E systems simultaneously.
