CallManager Upgrade & Extension Mobility Upgrade

Hi,

We are currently running CM 3.2(2c) with EM on the publisher and we would like to upgrade to CM 3.3(2spB) and we have about 200 IP Phones using EM.

We would like to know if the might be a problem with the EM status of the IP Phones after the upgrade. After the publisher is upgraded will he still know who is logged in and who is logged out of the phone or will we have to manually reset all the phones.

Thanks for your help,

Fred

Re: CallManager Upgrade & Extension Mobility Upgrade

I have seen many people having issues with the upgrade to CCM 3.2 extension mobility in this forum. One should make sure that the upgrade to the callmanager is complete before starting with the EM.

The above document has a good explaination of it.

Hope this helps.
