Upgrading Cisco Unity Connection
You need to upgrade from the current version of CiscoUnity Connection to a higher version to use the
new features supported with the new version. When you upgrade a server, the new version of Unity
Connection is installed in a separate disk partition known as inactive partition. To activate the new
version, you need to perform switch version. The following are the two ways to switch to the new
version:
•Automatic Switching: Allows you to automatically switch to the new version of Unity Connection
as part of the upgrade process.
•Manual Switching: Allows you to manually switch to the new version of Unity Connection after
the successful completion of upgrade.
If you need to revert the server to the previous version, you can rollback to the previous version.
Note You can install or upgrade Unity Connection 10.0(1) and later releases only on virtual machines.

Upgrade Types

The Unity Connection upgrade files are available as ISO images or COP (Cisco Option Package) files.
You can use either of the following interfaces to upgrade Unity Connection:
•Command Line Interface (CLI)
•Cisco Unified OS Administration web interface.
You must save the COP files on a Network Location FTP/SFTP server accessible during upgrade. ISO
image can be saved on a local DVD or on a network location. The performance of the upgrades can be
monitored through CLI or Cisco Unified Operating System Administration interfaces.
The Table 3 -1 explains the upgrade types and supported upgrade paths from one version to another.
