Efflux Migrator
Migrate across On-Premises Exchange
Don't hit a dead end with your cross-forest Exchange moves. Efflux Migrator efficiently migrates Exchange mailboxes across any two Active Directory forests, including their passwords and data.
Transition Your Messaging to Microsoft 365
Move mailboxes both ways: onboard from on-premises Exchange to Microsoft 365, and offboard from Microsoft 365 back to on-premises Exchange.
Want to Export Mailbox Passwords?
If you want to export passwords along with your mailboxes, just install the ADMT tool on the target server, the Password Export Server on the source server, and establish a trust relation between your source and target DCs.
