The first step in the migration process is to update these values so that all users connect to OWA, EAS, and OA via Exchange 2013. OWA – (Redirect) Should be pretty straight forward.Again, I won’t go into the details of why, but essentially Exchange 2013 can proxy and redirect back to 2007, but 2007 cannot proxy forward to Exchange 2013. When a user whose mailbox still resides on 2007, accesses OWA via the 2013 CAS, they will be redirected back to 2007 via external URL value: https://legacy.domain.com/owa Active Sync – (Proxy) I prefer to force Active Sync to proxy from 2013 to 2007 as some Active Sync devices don’t handle the redirect correctly.DNS must be updated however so that the A record for Autodiscover.resolves to the 2013 CAS.
For OA to proxy from 2013 to 2007, the IISAuthentication Methods on 2007 must be reconfigured to support both Basic and NTLM.
By default, Exchange 2007 IISAuthentication Methods is set to just Basic. Set-Outlook Anywhere –Identity “Ex2013\Rpc (Default Web Site)” –Internal Hostname webmail.–External Host Name webmail.–External Client Authentication Method Basic –IISAuthentication Methods Basic, NTLM Auto Discover – Both the 20 SCP locator can be configured to point to the Autodiscover URL https://autodiscover.domain.com/Autodiscover/
Transactions 3 and 4: show the DHCP server updating the forward map and reverse map DNS.
These tranasctions are illustrated in the examples that follow.
While this is extremely useful for IPv4 it is practically essential for IPv6.
Note: The configurations assume use of ISC's DHCP verion 4.x unless otherwise noted.
A good article to start with is Exchange 2013 interoperability with legacy Exchange Versions by Michael Van Horenbeeck. A single Exchange 2007 server and a single Exchange 2013 server. So I usually setup some dummy URLs on the 2013 side and test all the connections (OWA, EAS, OA).
This article points out when Exchange 2013 will proxy connections to 2007 vs. Both servers are installed in the same Active Directory Site. This way I know all proxying and redirecting is working prior to making any user impacting changes.

This page describes using and configuring DHCP for IPv4 (DHCPv4) and IPv6 (DHCPv6) to enable automatic updating of both the forward and reverse mapping zone file.
In general, when a PC/server, configured to use DHCP (a DHCP Client), is booted it attempts to make contact with a DHCP server by sending a UDP DHCPDISCOVER message (to port 67) using the local network broadcast address (though RFC 2131 explicitly uses the value 255.255.255.255).
