Call Manager Upgrade

[Mojo1]

We currently have CCM 3.3.5 on a Windows Environment. We will be upgrading to CCM 6.0 on a Linux Environment. We recently ran into some trouble while trying to upgrade from 3.3.5 to 4.2 with a mismatch version error. Can any suggest a way to make the transition from where we currently are to where we want to go without having to re-enter all the devices into call manager?

Hi,

4.2 should be supported for an upgrade of 3.3(5), perhaps you ran into os version error, where the current os does not support 4.2.

You can check requirements at:

Hardware might also be outdated, are you changing hardware in the process?

HTH, Avner.
