You must verify that there is no activity on the Avaya Breeze® platform servers in the cluster before continuing with upgrading.
Procedure
In System Manager, click Elements > Avaya Breeze®.
In the navigation pane, click Cluster Administration.
In the row for the cluster you are upgrading, look at the Activity column.
Verify that the Activity is 0.
You can view the Activity for individual servers in the cluster by clicking Show in the Details column.
After stopping new services, it can take a couple of hours for activity to reach zero. If activity has not stopped in a reasonable time, you can choose to proceed with the upgrade. Active calls will continue, but snap-in call control stops.
