MX100 changing ISP

[Rayw]

I have an MX100 and am changing ISP so I will have a new set of public IPs.  Is there a way I can configure all these changes to NAT rules and WAN interface a head of time to and then apply the changes to make the cut  over faster rather than at time of cutover doing all the config changes then?

You can use the 2nd wan port

When you are done, set the primary interface to wan2

Great answer by @ww .

Another option with regard to the NAT rules - just add them now.  They are only NAT rules so have no idea whether the address is correct or not.  They just won't do anything until you configure the WAN interface with the new addressing.
