Version 8.0 of Quest Migration Manager for Exchange has been enhanced to help users manage their e-mail migration. Features such as coexistence and ZeroIMPACT™ on the end user ensure no interruptions during the entire migration. This tool synchronizes mailboxes, distribution groups and public folders, lowering network bandwidth and shortening the migration project.
