I have found numerous information concerning this issue and thank everyone in advance for all of their insightfull assistance. We will be upgrading to new servers and configuring the new servers to the same server names and IP addresses (so that we do not need to do a DNS change). My question is: Once we have performed the installs and moves / migrations what exactly happens to the OWA site? We have a lot of OWA users and I do not want to take a chance of them not being able to access their email. As I stated we do not want to have to make a DNS change and want them to be able to continue to use the URL they currently have. Thus my concern on what happens to the OWA site.
