I have a customer that is deploying a DR data center. They are going to have OTV as an option to have to not change IP addresses when failing over VMs.
The network team has raised the point that failover the internal VMs and keeping the same IP is no problem but that could be tricky in regards to the DMZ.
Within the DMZ they are running Exchange OWA (UAG). I can use SRM to fail over this VM and change the IP during the process. If this IP changed how much, if any, manual changes would need to be made in order to get mail flowing? Could Exchange be preconfigured to allow this to work no matter what the IP of the OWA server is using cost / prioritization etc.? Have you ever had to deal with a scenario like this one?
Can anybody provide your thoughts?
