Moving system to new IP.

I'm looking at moving a Unity Express box and a 3560 switch to a new ip. I was hoping to try this on one or two phones as a test before moving the entire thing, but am not sure if that is "doable". As the system is currently working fine, it seems like it would just be a matter of re-iping the devices and changing the gateway information. However, experience has shown me that things don't always go so smoothly.

Has anyone out there done this type of thing on a production system? If so, what were your steps and how much downtime did you have?

Any tips or advice will be appreciated.

Thanks.

Re: Moving system to new IP.

I've done this a few times -

I'm a big fan of the 'config replace' command. It's the often overlooked cousin of 'configure terminal'.

You do a find-and-replace on your old IPs, put it on a TFTP/FTP server, and then do a config 'swap'.

There are some things it will not do like change the 'sccp ccm' ip addresses because it requires taking it out of a group and the likes, but it will mostly do the job.

Take care to notice the configuration in CUE also, like the sip subsystem gateway address, NTP address, etc.

Re: Moving system to new IP.

Thanks for the response, Nick. I will have to dig a little deeper to make sure I cover the two things you listed here. Hopefully it will go smoothly.

I'll update the thread with the results if we proceed with the switch over.
