Upgrade the Connector Host Expressway used for your Hybrid Services

Procedure to upgrade the Expressway cluster used for hosting Hybrid Services connectors. Does not apply to unclustered Expressways.

    1Sign in to Control Hub and find the connector host Expressways.
    2Put the primary node into Maintenance Mode.

    See https:/​/​collaborationhelp.cisco.com/​article/​nxep7tb for detail.

    The users allocated to that connector host node are redistributed to other nodes in the cluster.


    DO NOT use the Expressway's UI to enable maintenance mode, because the connectors ignore that configuration. When you correctly set maintenance mode, using Control Hub, then a banner on the Expressway's connector management page shows that Cloud Maintenance Mode is active.

    3Switch to the Expressway UI, and upgrade the node using the standard procedure for Expressway.

    See the release notes for your version at the Cisco Expressway Series Release Notes page.

    4Return to Control Hub after the Expressway has finished its upgrade and has restarted.

    You may see clustering alarms on Expressway or Control Hub. These should clear after you complete the upgrade across the cluster.

    5Return the primary node to normal service (disable maintenance mode using Control Hub).
    6Enable maintenance mode on a subordinate node in the same cluster.
    7Upgrade that node using the Expressway UI.
    8Return that node to service by disabling maintenance mode in Control Hub.
    9Continue in this pattern until the whole cluster is upgraded.

    Clustering alarms should clear soon after all nodes are upgraded.
