I was hoping to configure a "redirect" or "proxy" to point back to the other IP address at DC1. So I could make my DNS update to point to the IP address at DC2 and have the LTM direct traffic back to DC1 until the cutover date.
My understanding of a standard redirect is that it alters the URL or header from https://www.mine.com to https://1.1.1.1 (redirected URL). This would cause a problem with the SSL cert not matching the header of https://1.1.1.1
Maybe it's done easier by registering an additional DNS name. I just was told that a relay was possible, but I'm not familiar or finding much on a relay function of IIS or the LTM.
I hope I'm making sense.. I start to confuse myself and I'm usually a pretty savvy guy.
