CUCM & CUE Integration -> Loose all voicemail messages ?

[aeriksson]

Hi!

We are going to change an existing CME + CUE installation so that the site registers to a CUCM instead, but we are keeping the CUE.

CUCM v7.1.3 and CUE 3.2.

We found in a cisco document with Documen ID6002 "Call Manager for Cisco Unity Express configuration example" the following statement:

"Note: There is no method to convert or backup and restore from a Cisco Callmanager Express integrated with UE to a CUCM integrated with CUE or vice versa. The cad must be re-imaged. This means that you mist reapply the sw and license, and all configuration and data, which includes voice mail messages, are lost"

Is this correct? We will loose all voicemails and have to start from scratch?

The document is attached --look under the "Components Used" section.

Thanks in advance for any hints here!

Hi Annika,

The main thing here is that you will need will need to re-build the whole configuration

(including licenses) due to the fact you are moving from CME to CUCM. Here is the

related note;

Note: There is no method to convert or back up and restore from a Cisco CallManager Express integrated with Cisco Unity Express to a Cisco CallManager integrated with Cisco Unity Express or vice versa. The card must be re-imaged. This means that you must reapply the software and license, and all the configuration and data, which includes voice mail messages, are lost.

Sadly this limitation still applies even in CUE 7.x

If your system is already configured, you cannot change the license type from Cisco Unified Communications Manager to Cisco Unified Communications Manager Express or vice versa. To change your license type, you must first reinstall Cisco Unity Express and then change your license type before you configure your system in any way.

This limitation does change with the release of CUE 7.1(x)

Configuring the Call-Agent

Beginning with Cisco Unity Express version 7.1 and the use of CSL licenses, the call agent is no longer determined by the license.

However, you must configure the call agent by selection whether you are using Cisco Unified CME or Cisco Unified Communications Manager, using one of the two following methods:

•During the post-installation process

•After the service module boots up using the call-agent command

Hope this helps!
