Have been getting some training from other instance admin on how to configure this. Will require a lot of changes to accomplish this change. So will be looking into setting this up later next week once I have accommodated all the basic stuff that needs to be done first. Once this is ready to be done I will let you know then deploy it to this site and (hopefully) not cause downtime during the change.

you do have to get the SSL settings right but we will.
