We are about to change public IP addresses. This includes for our firewall, internal servers, and our Exchange server. I know that I will need to make the changes to the A and MX records at our hosting company, and change the IPs on the firewall, but will there need to be any changes to the Exchange server itself? We also use OWA which required us to get an SSL for the secure connection. Will this need to be modified, or will another SSL cert need to be created? I also know that we will need to have the PTR record changed.
Am I missing something? I really dont want to break the mail during this transfer.
Thanks a buch yal.
