Migration and upgrade overview

---

Upgrading Cisco Unified Communications Manager requires careful planning and an understanding of the impact on call processing during the upgrade. When an upgrade includes virtualization, a number of problems can occur if you do not follow the correct procedure.

This document outlines procedures to upgrade Cisco Unified Communications Manager to Release 9.1(1) or later, while at the same time migrating the server to a virtual machine. The procedures described in this document are designed to ensure that you successfully migrate all server functionality and licensing to Release 9.x.

Choose the procedure below that best fits your scenario and follow it.

Upgrade path considerations

The first task in moving to a virtual deployment of Cisco Unified Communications Manager is to determine the appropriate upgrade path and steps to follow. Typically, the older the release that you start from, the more steps or caveats you may find along the way. This document is designed to inform the persons who are performing the upgrade of the most efficient upgrade method.

While this document covers most upgrade scenarios, there will inevitably be some that are not covered. Even though this document explains the steps and why they are recommended, there may be exceptions to certain steps or potential alternatives.

The document Supported Servers for Releases of Cisco Unified Communications Manager on Cisco.com contains a complete hardware compatibility list.

The table in the Server support section lists all known server types and the recommended upgrade paths to follow. Read the comments section in the table for information about special considerations.

Note	The “Related documentation” section, below, contains the list of all documents referred to in this document.

Release 9.x licensing differences

• Cisco Unified Communications Manager Release 9.x licenses and license enforcement is completely user-based, matching how licenses are ordered. Customers no longer order user-based licenses and receive DLU-based licenses to upload to the customer Cisco Unified Communications Manager publisher.
• There is no mechanism to upload DLU-based licenses to a Cisco Unified Communications Manager Release 9.x publisher. Cisco Unified Communications Manager Release 9.x licenses must be applied to an Enterprise License Manager server, which only accepts the new user-based licenses.
• Cisco Unified Communications Manager Release 9.x licensing no longer includes or requires any node or software release licenses.
• Cisco Unified Communications Manager 9.x clusters can operate in a full featured demo mode for 60 days without a license. After 60 days, Cisco Unified Communications Manager clusters continue to operate and route calls, but the functionality to add or remove devices and users is disabled until valid licenses are supplied by an associated Enterprise License Manager.
• Cisco Unified Communications Manager Release 9.x licenses are tied to the identity of the Enterprise License Manager server, rather than to the publisher MAC address or licensing MAC.

For information on licensing updates between Release 9.0(1) and 9.1(1), see the “Licensing” section in Release Notes for Cisco Unified Communications Manager, Release 9.1(1).
