Migrating to Exchange 2013 – Options for migrations from Exchange 2003 to Exchange 2013

I want my business to use Exchange 2013, but how do I get there?

Migrating to Exchange 2013 can be seamless and uneventful with the right partner and solution.  However, there are many options available to get to this destination.  The goal of this document is to provide a simply overview of the different options available.

Current Version?

An important first question to ask is what the current version(s) of Exchange are in the environment from which you intend to migrate. Exchange 2013 CANNOT be installed in the same AD Domain or Forest in which Exchange 2003 or earlier is also installed.  The Exchange 2013 installer will perform many health and status checks to determine if it is safe to install.  An existing installation of Exchange 2003 or earlier will be caught and prevent the installer from proceeding.  Furthermore, any remnant of Exchange 2003/2000 will also block the installer. One of the risks associated with attempting to migrate to Exchange 2013 from an old version is that you may not be able to uninstall the old Exchange platform to the liking of the Exchange 2013 installer.  At that point, you must search for answers on the internet and take the advice of others which may or may not exactly apply to your environment. Exchange 2007 and later can live side-by-side in the same forest with Exchange 2013, however this pattern does not end with Exchange 2013.  When the next version of Exchange is release, Exchange 2007 will have the same issue that Exchange 2003 has today.   Download Free White paper for additional information – Exchange 2003 Migration Options
