My current situation is that i have 8 ASA site to stie vpn connected together. My company is changing isp providers and we wont' be using the same ip address anymore on two of the sites. I know i have to change the outside ip address on the ASA for the two sites but how do i configure the vpn with the new ip address? Do i need to configure ASA again from scratch and use the vpn wizard to connect all my sites? And if do have to configure from scratch how do i remove the old tunnel and ip address from the other ASA?
