Back in October, Microsoft announced that the Release to Manufacturing (RTM) build of Exchange Server 2013 was signed off. Since that time, Microsoft has been focusing their efforts on releasing the next version of Exchange through multiple distribution channels to business customers.
Today, Microsoft has reached another important milestone - The Exchange team is excited to announce in 12 Feb 2013 the Service Pack 3 is a fully slipstreamed version of Exchange 2010.
For those of you who wish to roll out Exchange Server 2013 in greenfield environments, or in labs and test environments to evaluate new features and test with LOB applications, you can start right away. If you are running an Exchange 2010 or 2007 environment, you'll need Exchange Server 2010 SP3 or 2007 roll up in order to upgrade.
If you haven't already, we encourage you to learn more about Exchange Server 2013 by reviewing TechNet documentation or attending an Ignite training session. It's a good idea to evaluate prerequisites and system requirements at this time, as well as become familiar with Exchange's simplified building block architecture, so that you can get a head start on hardware sizing, planning and purchasing.
