Question : How to redirect incoming IP traffic to remote network?

Perhaps I am using the wrong terms in my search but I can't find any soluitons to my issue.
I am trying to configure ALL traffic destined for one public IP to be forwarded or redirected to another
remote network public IP.

98.100.100.1 -> Incoming IP Request

Received on Cisco Router

Immediately Turned Around

Outgoing IP Request Forwarded -> 200.100.100.1

Both networks are independent.

The reason for this is to combat DNS Caching duiring a server migration from one numbered
network to another.

Thanks for any suggestions.

So then you'll still need what I first suggested, a 1-to-1 NAT from 98.100.100.25 to 200.100.100.25, except this will be defined as an outside to outside NAT.  The reason you need a NAT is because traffic destine to 200.100.100.25 needs to return through the same path as it came from.  If not the connection will break.  Unfortunately the Cisco IOS does not support this type of NAT.

You're next best option is to create a VPN tunnel from router 1 to router 2. Since you were NATing 200.100.100.25 to 172.16.100.2 you can try this:
-Define a private subnet for this tunnel (ex 172.16.200.x).
-Router 1 will have 172.16.200.1
-Router 2 will have 172.16.200.25
-On router 1 define a NAT from 98.100.100.25 to 172.16.200.25 (this will be routed through the VPN tunnel)
-On router 2 define a NAT from 172.16.200.25 to 172.16.100.2
