Recently, the Microsoft Exchange 2010 Service Pack 1 is available. For many it is the starting signal for updating the platform. At least in terms of Exchange 2010 migration, it seems to be a hot autumn. Various large companies and institutions of the civil service plan to switch. Exchange 2010 since November 2009 on the market, but most user companies are waiting to migrate to the first service pack. SP 1 is now available, so the change from the previous 2007 or often even to begin release of 2003. Migration is often risky. How long will it take, how expensive and complicated it is, how much it interferes with the operation? These are all questions that arise in connection with migration projects.
Therefore, I am providing some tips, first of all pointed out that Microsoft itself does not speak of a migration, but by a transition, ie a gradual transition from the previous version to the current release. Exchange 2010 can be good, if necessary, longer co-exist with its previous versions. This reduces the pressure to migrate quickly and completely. A switch to Exchange 2010 is divided into different phases. The migration and the nature of the future Exchange 2010 server must be planned carefully. A direct migration from Exchange 5.5/2000 to Exchange 2010 is not possible. In this case, you should update via Exchange 2003 or 2007 will be accepted.
