CASE STUDY

ITSC GmbH Performs Cross-Forest Migration of 1,700 Email Users from Exchange 2003 to Exchange 2010 in a Single Weekend

 

“Our goal was to migrate over the weekend and we achieved it with no impact on our users. Our users were very happy to get the new features when they came back to work on the following Monday morning.”

- Karsten Schmidt, Systemadministrator, ITSC GmbH

 

Ready for New Capabilities

Headquartered in Hanover, Germany, ITSC GmbH provides statutory health insurers and other companies in the German healthcare market high-performance services and It solutions under one umbrella.

ITSC GmbH, a technology provider in Germany, had two good reasons for migrating to Exchange 2010. First, Microsoft was planning to stop support for Exchange 2003, the messaging platform previously used by ITSC. second, ITSC wanted to begin using the new features in Exchange 2010 like the high-availability capabilities enabled by Database Availability Groups (DAGs).

ITSC managers needed to plan a one-to-one, cross-forest migration for 1,700 users located in five company offices across Germany. Another critical goal was to complete the migration over a single weekend in order to avoid a negative impact on users.

Identifying the Right Migration Partner and Solution

Based on positive experience with previous Exchange, Active Directory (AD) and Identity Management projects, ITSC chose infoWAN, a Binary Tree, and Microsoft Partner, to perform the migration to Exchange Server 2010. infoWAN, a management consultancy based just outside Munich, has the expertise and experience necessary to successfully perform cross-forest exchange migrations and upgrades.

To make the mailbox migration easier to accomplish, infoWAN recommended the Binary Tree Exchange Pro software which:

  • Automates migration of user mailboxes to the Exchange 2010 environment
  • Simplifies management of the migration for IT administrators and technical staff
  • Migrates mailboxes cross-forest, without an active directory trust

Migrating Users and Mail in One Weekend

infoWAN helped ITSC to prepare for the migration and provided the troubleshooting during the migration. ITSC and infoWAN benefited from Exchange Pro’s easy-to-use user interface and its comprehensive reporting and scheduling capabilities. Exchange, which utilizes Microsoft Powershell to migrate the data, swiftly migrated the 1,700 user mailboxes, which ranged in size from 200MB to 2GB or more.

To move the user directories, the migration team used Microsoft’s Active Directory Migration Tool. Overall, the migration went smoothly and was deemed a success as it was completed during the planned weekend without impacting the ITSC users.

A Successful Transition to New Capabilities

The key goal of the migration was to give users new messaging capabilities without interrupting their work. “Our idea was to migrate over the weekend and we achieved it with no impact on users,” says Karsten Schmidt, System Administrator, ITSC GmbH. “Our users were very happy to get the new features when they came back to work on the following Monday morning.”
