URIs in exchange 2007 coexistence with 2013

Hi

I have exchange 2013 CU2 and exchange 2007 in coexistence.  I have created legacy.domain.com and owa redirection works.  However I am totally confused about how to re-adjust other URIs. 

Would you please advise?

Legacy.domain.com --> Internally & externally points to exchange 2007 CAS

mail.domain.com --> Internally & externally points to exchange 2013 CAS

Exchange 2007 ==> 

Set-ActiveSyncVirtualDirectory "https://legacy.domain.com/Microsoft-Server-ActiveSync"
Set-WebServicesVirtualDirectory "https://legacy.domain.com/EWS/Exchange.asmx"
Set-OabVirtualDirectory  "https://legacy.domain.com/OAB" 
Set-OwaVirtualDirectory -Identity "https://legacy.domain.com/owa"
Set-ClientAccessServer -AutodiscoverServiceInternalUri  https://mail.domain.com/Autodiscover/Autodiscover.xml

./,/,/,/,/,/,/,/,/,

Exchange 2013 ==> 

Set-EcpVirtualDirectory https://mail.domain.com/ECP 
Set-Webservicesvirtualdirectory https://mail.domain.com/EWS/Exchange.asmx
Set-ActiveSyncVirtualDirectory "https://mail.domain.com/Microsoft-Server-ActiveSync" 
Set-OwaVirtualDirectory https://mail.domain.com/OWA 
Set-ClientAccessServer -AutoDiscoverServiceInternalUri "https://mail.domain.com/Autodiscover/Autodiscover.xml"
Set-OABVirtualDirectory "https://mail.domain.com/OAB"
