Configuring OWA virtual Directory for Legacy redirection

Almost ready to start moving users.  All that's left is to change my NAT policy to point our MX record to the Exchange 2010 server and to configure the 2010 OWA virtual directory for legacy redirection.  My question is, in the following syuntax:

Set-OWAVirtualDirectory <CAS2010>\OWA* -Exchange2003URL 

Is "<CAS2010>\OWA*" the internal name of the 2010 server or the external ""?  Thanks.

yes you can have the different url for internal and external access.

but Set-OwaVirtualDirectory desn't have any parameter like -Exchange2003URL

but you can use the parameter -LegacyRedirectType to set the url for your exchange 2003

the above command is taken directly from an Exchange 2003 to 2010 Migration Guide that I purchased.  Are you saying that is not the proper way to set the OWA legacy redirection?  

Madan SharmaConsultantCommented:
Apologies ! you can use the same as you mentioned. and the parameter provided by is set to redirection type i.e. it will be silent redirect or manual

Right, but my question is:
The first directory that is listed, <CAS2010>\owa, is that the internal server name (myserverne\owa) or would it be the FQDN (\owa)?
It is myserverne\owa.
Please note that you can not use
