Rolling back to the earlier version

Last Updated : Jun 10, 2026 |

About this task

If you have performed at least one upgrade on your system, then you can roll back to the earlier installed version. Avaya Aura® Web Gateway is stopped while the rollback is in progress.

If you perform a rollback after changing Avaya Aura® Web Gateway IP addresses or FQDNs, Avaya Aura® Web Gateway will continue using these new IP addresses or FQDNs after the rollback. The rollback process does not revert IP address or FQDN changes.

Before you begin

You must verify that it is possible to roll back a cluster by ensuring that all the nodes in the cluster have the same inactive version available. Do not attempt a cluster rollback if all nodes cannot rollback to the same inactive version. Run the following command to display the inactive version on each node:

cat /etc/ucapp.properties | grep UCAPP_CAS_INACTIVE

Procedure

  1. Open the Linux shell using your Linux administrator account credentials.
  2. To roll back to the earlier version, run the app rollback command.

    In a cluster, roll back each node one at a time. Roll back the seed node last.

  3. After the rollback is completed, restart services by running the svc csa restart command.

    If the node is part of a cluster, complete the rollback on the other nodes, one at a time, before restarting any of the cluster nodes.
