Hi All,
I�d be very grateful if anyone could confirm or correct my thoughts on a namespace concern. I�m currently going through the deployment plan for transitioning my 2007 2 node CCR to a 2 node 2013 DAG. The only thing I�m a little stuck on is around changes to the namespace.

In my organisation we don�t use TMG or OWA and any remote workers have to connect via VPN, so essentially exchange is only accessible �internally� using Outlook.

Currently there doesn�t seem to be a traditional namespace configured, there are two SCPs in AD, one for each of the two Hub/CAS servers we have, and are configured to use the server�s FQDN. If people want to use OWA, they just use the FQDN of a CAS

Every guide I see states that you have to re-configure your 2007 URLs so as to be different from the 2013�s, so that 2013 will be able to redirect clients to the legacy 2007 database if their mailbox hasn�t been moved to 2013 yet.

In the 2013 install I want to use a more appropriate namespace such as mail.dagclustername.local and don�t see why I have to go through the added complexity of changing the existing 2007 SCP URLs when it�s different to 2013�s anyway?

I think this is the crux of my confusion, I don�t have any external URLs and my internal URLs for 2007 and 2013 will be different anyway, so why create the legacy.domain.local for the co-existence phase?

Sorry for the long post,and my first too! Your thoughts and comments are great appreciated :-)
