Netgate m1n1 question

[hatboy]

I just purchased one of those netgate appliances and have a quick question.
Our current network's IP range is 10.10.0.1 to 10.10.0.253. By default, pfsense uses 192.168.1.1.
How can I safely change the IP range of the pfsense appliance to 10.10.0.1? I tried doing this in the VMWare version but was then locked out after each attempt. I dont want this to happen to me on the appliance as I have no way to reinstall pfsense in case anything goes wrong.

On the console, change the appropriate interface IP to your chosen range using the menu.
