active media sessions present. When this occurs, it is safe to proceed
with the upgrade without affecting service.
If an upgrade fails during the initial stages, a rollback to the previous
load is performed. A notification of the failure appears within the System
Management Console.
If a component upgrade fails after the initial stages of the upgrade, it
does not rollback automatically. A dialog box appears in the
Management Console stating that the upgrade failed and prompts the
administrator to determine whether a rollback should be performed.
The length of time required to complete an upgrade is approximately 30
minutes. While there is no impact to call-processing services, perform
updates during low traffic periods to minimize reduced capacity.
