Upgrade an X8.n Cluster to X8.7
This procedure describes how to upgrade an existing X8.n cluster to X8.7.
When you select an upgrade window:
■
Choose a period of low activity
■
Allow time to upgrade all peers in the same window. The cluster will not reform correctly until the software
versions match on all peers
versions match on all peers
Prerequisites
For each Expressway peer (including the primary), check the Alarms page (Status > Alarms) and ensure that all alarms
are acted upon and cleared.
are acted upon and cleared.
Upgrade Expressway Cluster Peers to X8.7
Note
: To avoid the risk of configuration data being lost, in addition to maintaining service continuity, it is important that
you follow the upgrade instructions in the order specified here. In summary, we recommend that you:
1.
Upgrade and restart the primary peer first.
2.
Upgrade the other subordinate peers and then restart them one at a time.
Full instructions are provided below.
Upgrade the Primary Peer
1.
Log in to the primary peer as admin on the web interface.
2.
Backup the Expressway (Maintenance > Backup and restore).
You should backup your system before upgrading. If at a later date you need to downgrade to an earlier version,
to restore the configuration you will need to restore a backup made against that previous release.

3.
Enable maintenance mode:
a.
Go to Maintenance > Maintenance mode.
b.
Set Maintenance mode to
On.
c.
Click Save and click OK on the confirmation dialog.
This will stop the primary peer processing any new calls (existing calls will be dropped only if a restart occurs;
other cluster peers will continue processing calls)
other cluster peers will continue processing calls)
4.
Wait for all calls to clear on this peer.
If necessary, manually remove any calls on this peer that do not clear automatically (using the web browser go to
Status > Calls, then select the check box next to the calls you want to terminate and click Disconnect).
Status > Calls, then select the check box next to the calls you want to terminate and click Disconnect).
5.
Upgrade and restart the primary Expressway (Maintenance > Upgrade).
For any further details see the "Upgrading Software" section of
Expressway Administrator Guide.
Note that the web browser interface may timeout during the restart process, after the progress bar has reached
the end. This may occur if Expressway carries out a disk file system check – which it does approximately once
every 30 restarts, or if it has not checked its disks in the last 6 months.

Upgrading of the software on the primary Expressway is now complete.
Cluster-related alarms
You can ignore any cluster-related alarms that occur during the upgrade process, for example:
