Transfer VPN device to new site

I have a Cisco 1811 from one of our offices that has been shut down.  I would like to now use this router at a new site.  The old site used DHCP and the new site can use the same address scheme.  The tunnel information should be the same.  I know that I need to change the wan interface to the new wan address of the new site.  What other settings would I need to change to get this working?   I am testing it from my home and have been unable to get the tunnel up.  I connected my cable modem to FE0 and changed the ip, and it connects okay.  The remote sites use our DNS so that wouldn't need to be changed.  I plugged into one of the ports and received an IP.  Any tips on getting the tunnel up, is there a command I need to run on the router on the other end?  Thanks.

You need to change the Addrss on the other device to refelct your New WAN address since that is what it looks for.

SO just change the wAN address on the remote, and the target VPN address on your main site device.

I hope this helps !

Thank you for the reply, I just found out that we are using DMVPN.   Does that change things as far as what I need to to get the new site up and running?
