Upgradation of CCM from 4.0(1) to 4.0(2a)


I have a cluster of CCM 4.0(1). of 2 subscriber and 1 publisher. Now I want to upgrade it to 4.0(2a).

Can anyone suggest the Preupgrade, postupgrade tasks.

What are the components required for doing the upgrade.

Thanks in advance.

One more thing which I forgot to ask. Do I need the whole set of CD's of 4.0(2a) for up-gradation.

Do you have CCO account on the I'm not sure if these links will work without CCO account.

Here is a link to all CallManager installations and upgrades documentation. Just go to the "CallManager 4.0" section and click the link you need:

I would recommend using the "Upgrade Assistant" before starting the upgrade - it will check all required pre-requisites for a upgrade.

You have to upgrade your CallManager to the version 4.0(2), and then download and install SR2a upgrade.

First you have to upgrade the Publisher, and then a Subscribers. In most cases a Subscribers will not be able to communicate to the Publisher until upgraded to the same release, so, you have to upgrade whole cluster at once.

Good luck,
