CallManager IP Address change

[tomchan]

We need to change the ip addresses in our CCM4.1 (both pub and sub). We want to confirm if CCM4.1 need to be reinstalled and all the ip phones database need to be reinstalled again, for example BAT.

Thanks.

It seems like reinstalling all the CCM software and BAT is not necessary, and I believe it'll apply to CCM4.1 as well. Please advice. Thanks.

The DOC is fine, except for one thing. It does not mention gateways. When you change the IP address, you will need to make the appropriate changes to the gateway configs as well. A reinstall is not necessary.
