Cisco Unity Connection 10.0(1) and later releases can only be installed on virtual machines. Physical servers are not supported to install or upgrade Unity Connection 10.0(1) and later, and an attempt to install or upgrade Unity Connection 10.x on physical servers will fail.
An upgrade from Unity Connection from version 7.0.2 to 10.5 will consist of the following major steps: 7.0.2 to 7.1.3 7.1.3 to 8.0.2 8.0.2 to 10.5.1
There is an additional step of backing up Unity Connection 7.1.3 on MCS and restoring it on exact 7.1.3 version on UCS.
Please find the details below.
***** Task List for Migrating from a Unity Connection Physical Server to a Unity Connection 10.x Virtual Machine*****
1. Review the section “Requirements for Installing Cisco Unity Connection 10.x on a Virtual Machine” in System Requirements for Cisco Unity
2. In the Cisco Unity Connection 10.x Supported Platforms List , in the table of virtualization specifications, determine which VMware configuration you want to deploy on the Unity Connection server, based on the maximum number of ports and the maximum number of users. Then make note of the VMware OVA template that corresponds with that configuration. The document is available at:
3. Download the VMware OVA template that you identified in Task 2. See the “Installing Cisco Unity Connection for the First Time on a Virtual Machine” section in the applicable Release Notes for Cisco Unity Connection at:
4. If the Unity Connection physical server is running version 7.1(2) or earlier: Upgrade to Unity Connection 7.1(3). See the applicable chapter in the
Upgrade Guide for Cisco Unity Connection Release 7.x at:
http://www.cisco.com/en/US/docs/voice_ip_comm/connection/7x/upgrade/guide/7xcucrugx.html . (You upgrade to version 10.x in a later task.)
++++Caution: Running Unity Connection 7.1(3) in a virtual environment for any longer than is required for the migration is not supported.++++
4.1 As per the release notes for Unity Connection 7.1.3, you can upgrade directly to version 7.1.3 from version 7.0.2.
Also, as per the release notes for Unity Connection 10.5 http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/release/notes/10_5_1cucrn.html#pgfId-1957559
"You can upgrade from Unity Connection 10.0(1), 9.x, 8.x, and 7.x to Unity Connection 10.5(1). Note: To upgrade from Unity Connection 7.1(5x) and 7.1(3x) to Unity Connection 10.5(1), you must first upgrade to Unity Connection 8.x."
5. Provision the physical host where the Unity Connection virtual machine will run, according to the “Requirements for Installing a Cisco Unity Connection 10.x Virtual Machine” section in System Requirements for Cisco Unity Connection Release 10.x at:
6. Deploy the OVA template that was downloaded in Task 3. to create a virtual machine and configure it.
7. In the VMware vSphere Client, configure the virtual disks that are assigned to the Unity Connection virtual machine in independent-persistent mode. This provides the best storage performance.
8. On the virtual machine, change the BIOS setting so the virtual machine boots first from the DVD virtual device, then from the virtual hard disk. See the “Changing the Boot Order of the Unity Connection 10.x Virtual Machine” section.
9. If you are migrating from Unity Connection without cluster, follow the steps given in the “To Migrate from Unity Connection without Cluster” section.
