We have a production server with SBS 2003 and Exchange.
Only 9 users
Purchased a new server with 2012 R2 and purchased licensing for Exchange 2013 Standard

Can we simply:
install and license Exchange on the 2012 Server
dump everyone's mail to a PST and load into new server
configure everyone's Outlook profile to look at new server
configure firewall for new exchange and OWA destination

Or will doing this break the SBS rules and set off a reaction causing SBS to become upset and turn off

Also we need to  (for other reasons) keep the SBS server in production for another 2 months


thanks

Note, there is not direct upgrade path from Exchange 2003 to Exchange 2013, you may need to temporarily install Exchange 2010, remove Exchange 2003 and then Exchange 2013.
Or Export mailboxes to PST, Remove Exchange 2003 and then install Exchange 2013.

I understand there is not a direct upgrade.  I am fine with a manual dump and load of the mailbox data.  just wondering if there is any Active Directory or SBS-related issues with there suddenly being a new Exchange server in the neighborhood

in particular i am curious about the ramifications of having 2 Exchange servers on the same LAN\domain.  What would happen?  If i point all the Outlooks to the Exchange 2013 and we point incoming mail traffic from the firewall to the Exchange 2013 server and stop all the Exchange Services on Exchange 2003  - would things function?
