We are running OS Service Release 2000.4.3asr6 and CCM 4.1(3)sr4d. We want to upgrade CCM to Version 4.3(1), but it requires OS 2003.1.1 prior to the upgrade.

Is it possible to upgrade OS 2000 to 2003?

Thank you in advance.

From a Microsoft perspective I would not recommend an in-place upgrade from 2000 to 2003.

I would do a clean install of 2003 on a new server and use BARS to backup and restore CallManager. This would also give you a good fallback path.

Hi Jason,

We have to upgrade a callmanager 4.1(3) to a 4.3(1).

The CMM 4.3(1) supports only the OS 2003.1.1 or greather.

You recommand to make a freh install on the server and restore the datas by using the a Bars backup.

But is it possible to restore a BARS from a version 4.1 to a 4.3 ?

I think that to restore a bars, you must to it on an exactly version of callmanager ?

Thanks you in advance,
