This session will cover the tool and steps required to migrate from an Exchange 2003 or higher to Exchange 2013 in another forest. A high-level outline of the steps, scripts, Microsoft tools, and notes from the fields will be discussed. In addition, options for organizations still on Exchange 2003, which isn't supported by built-in scripts and tools with Exchange 2013, will be covered. Discussion will cover the scripts included with Exchange 2013 to migrate mailboxes across forests and how to migrate contacts, groups, policies, Public Folders, and other settings that aren't migrated by those scripts. The main focus will be the many additional steps, solutions, and scripts required to do a full fidelity migration. This session will mainly focus on the needs of small to medium companies (< 1,000s of mailboxes). Information discussed will be helpful to any size organization that needs to do a cross forest migration.
