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
Or Export mailboxes to PST, Remove Exchange 2003 and then install Exchange 2013.
