C H A P T E R 3

Upgrading Cisco Unity Connection

You need to upgrade from the current version of Cisco Unity 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.
