[c-nsp] VPN-3000 and PIX VPN peer change question?

[Scott Granados]

Hi, I have a question about upgrading a connection for a remote site and 
changing the VPN peer on a VPN-3000.

BACKGROUND
In the field I have a branch office with a Pix that provides their office 
connectivity and VPN tunnel back to HQ. The branch office is having its 
bandwidth increased by swapping to a new provider that offers a metro E 
package. The IP addressing of the firewall will change but all the other 
services and internal addressing remain the same.
    At HQ I have a VPN-3000 with that wonderful point / click thingy instead 
of a real usable command interface.  On the VPN-3000 I have a profile that 
sets up a lan to lan VPN (their wording) back to the Pix at the branch.

QUESTION
    My question is assuming the Pix in the field is updated and all other 
things work will I simply need to change the peer address on the VPN-3000 to 
reconnect the VPN? Also, am I correct in my thinking that you change the 
peer address under configuration / policies / ipsec / L2L/ (profile)? 
There's a peer address that matches my far end, are there any other 
instances or things I should adjust?  Pointers would be appreciated.  To me 
it looks like I make this one change and it should work but I want to make 
sure before I have a guy sitting in the field holding his shmeckle while I 
try to figure things out.:)

Thanks
Scott
