Exchange Archive mailbox to Exchange migration
Organizations often need to migrate archive mailboxes to a new or different on-premises Exchange server due to hardware upgrades, server consolidation, regulatory compliance, or end-of-life support for older Exchange versions. Migrating archive data helps centralize mailbox management, improve performance, and maintain long-term accessibility to important historical emails without relying on outdated infrastructure.
