2851 Router came in with CCME and CUE installed. IOS 12.4.6 and cue 2.3. I want to integrate CUE with CCM 4.2. Is it possible?
I found this statement I am not sure exactly what it means and how it is done.
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.
You cannot move the CUE config between CME and CCM. You will need to order the proper License for use with CCM. Have a look;
Your system probably came with a License like this for CME (Note the CME at the end of the part#);
Cisco Unified Communications Manager Express
12-mailbox package: SCUE-LIC-12CME=
What you really need is a License like this for CCM (Note the CCM at the end of the part#);
12-mailbox package: SCUE-LIC-12CCM=
From this good doc;
Upgrading or Downgrading the Cisco Unity Express License in the Same Version

Hope this helps!
