In part 1 we covered the deployments steps for Exchange 2013, in Part 2 of this series we covered Exchange 2013 configurations and testing, in this part we will start our migration. Make sure to start these configuration outside business hours, also plan a proper downtime to complete these steps and test them.
Open Exchange 2007 management shell and run the following commands.
Set-OwaVirtualDirectory -Identity "e12-01\OWA (Default Web Site)" -ExternalUrl https://legacy.contoso.com/owa
Set-OabVirtualDirectory -Identity "e12-01\OAB (Default Web Site)" -InternalUrl https://legacy.contoso.com/oab -ExternalUrl https://legacy.contoso.com/oab
Set-ActiveSyncVirtualDirectory –Identity “e12-01\Microsoft-Server-ActiveSync (Default Web Site)” –ExternalUrl https://legacy.contoso.com/Microsoft-Server-ActiveSync –InternalUrl https://legacy.contoso.com/Microsoft-Server-ActiveSync
Set-WebServicesVirtualDirectory –Identity “e12-01\EWS (Default Web Site)” -InternalUrl https://legacy.contoso.com/ews/exchange.asmx –ExternalUrl https://legacy.contoso.com/EWS/Exchange.asmx

Create/update your TMG publish rules
For Exchange 2007 update your publish rules to accept connections for Legacy name space:
Follow the steps in this link to publish Exchange 2013.
Update your DNS records as follows
Point to Exchange 2013 server
New record points to Exchange 2007 Server
Point to TMG Listener
New record Point to TMG Listener
Apply all your test scenarios for both internal and External client types; once again you can use Microsoft Remote Connectivity Analyzer
Once you complete your tests successfully, its time to start moving mailboxes. you can do this using EAC or Shell.
New-MoveRequest -Identity 'firstname.lastname@example.org' -TargetDatabase "DB01"
You can create Batch moves as described in this link. Once you complete your mailboxes migration let us move to the final steps in this migration process (PF Migration and Exchange 2007 Decommissioning).
As per my Experience, you just need legacy for owa and EWS.
