Exchange 2010 coexistence with 2013 (URLs to use??)

Hi

I have exchange 2013 CU2 and exchange 2010 in coexistence.  I need some help with URIs on both environments BEFORE I can change the DNS entries to point to 2013.   

Would you please advise?  Especially on what I should use for 2010 URLs.

mail.domain.com --> Internally & externally points to exchange 2013 CAS (Used to be FQDN pointing to 2010)

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"

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

Exchange 2010 ==> 

Set-ActiveSyncVirtualDirectory 

--> InternalURL:  "https://??????????/Microsoft-Server-ActiveSync"

--> ExternalURL:  $NULL
Set-WebServicesVirtualDirectory "https://??????????/EWS/Exchange.asmx"
Set-OabVirtualDirectory  "https://??????????/OAB" 
Set-OwaVirtualDirectory -Identity "https://??????????/owa"
Set-ClientAccessServer -AutodiscoverServiceInternalUri  https://mail.domain.com/Autodiscover/Autodiscover.xml
