Business SituationIn January 2004, Hannover Re decided to undertake a migration of its existing Windows and Exchange environment. The decision to migrate was to
The company also wanted to ensure that the current environment had high levels of stability prior to a major upgrade of its current ERP implementation.
SolutionThe organization implemented the Windows migration with Avanade over several phases: 1) project planning; 2) pilot migration; and 3) rollout to the remainder of the organization. The pilot program was designed to migrate all users over to the new Windows platform by June 2005 with the understanding that a majority of the work around the Windows platform would be completed in January 2005.
For the Exchange platform, the organization planned on deploying Exchange in the latter half of 2004 and continuing through the first six months of 2005. As of June 1 2005, all users were migrated over to the new platform.
ResultsA key benefit Hannover Re identified was the reduction in time-to-benefits. By using Avanade, the organization believes it was able to complete the migration to Exchange 2003 12 months faster than it would have without Avanade. Through a faster migration, Hannover Re was able to realize key benefits associated with the migration to Exchange 2003 — savings from server consolidation, improved Exchange availability, and better mobile and remote access — a year earlier than it would have realized without Avanade.
