Can i upgrade from CallManager 3.3(5) to 4.1(3) using the version of 4.1(3) available in the voice download section on CCO ??
From the release notes:
â¢Valid upgrades to Cisco CallManager 4.1(3) include Cisco CallManager versions 3.3(5), 4.0(2a), and 4.1(2). (You can use updated Cisco CallManager software kit CD-ROM disks that are available for this upgrade.)
â¢If your server runs Cisco CallManager release 4.0(2a) or 4.1(2), you can upgrade your server to release 4.1(3) by using the web download file that is available at http://www.cisco.com/kobayashi/sw-center/sw-voice.shtml.
â¢If your server runs a version of Cisco CallManager release 3.2 or earlier, you must use the Cisco CallManager software kit CD-ROM disks to first upgrade every server in the cluster to the latest version of Cisco CallManager release 3.3 or 4.0 before you can upgrade to a version of Cisco CallManager release 4.1
So, you will require upgrade media as the upgrade file downloadbale is only for upgrades from CM 4.0 and 4.1.2
