Introduction:
Migrating Microsoft Exchange Server mailboxes between different Active Directory domains is a complex undertaking, particularly when large volumes of mailbox data must be transferred over internet connections. The migration must preserve mailbox integrity, minimise downtime, and ensure uninterrupted business communication.
Om Enterprise Inc., a US-based managed IT services provider, needed to migrate 312 Exchange mailboxes containing approximately 1.5 TB of mailbox data from one on-premises Microsoft Exchange Server to another hosted in a different Active Directory domain. To complete the migration efficiently while minimising business disruption, the organisation selected Stellar Migrator for Exchange.
