You will need to upgrade your IOS to below:

12.4(11)XW9

—

4.2

4.2.0.4

Cisco Unified CME 4.2 Specifications

Also review my recent post here: https://supportforums.cisco.com/discussion/12435376/ios-upgrade-and-cme

IOS upgrade would upgrade your CME, if you need to you can upgrade phone loads and CME GUI according to the instructions in above link. Also confirm CUE complatability, that your CUE version is compatible with CME 4.2.
