   • Configure user accounts and mailboxes.
2. Set Up Migration:

   • Choose “+” and select “Migrate to Exchange Online.”
   • Select “Cutover migration” and follow the wizard to connect to your on-premises Exchange server.
3. Start Migration:
   • The migration batch will begin. Monitor the process in the Exchange Admin Center.
   • After completion, update DNS records to direct mail flow to Microsoft 365.
4. Post-Migration Tasks:
   • Configure Outlook profiles for users.
   • Decommission the on-premises Exchange server if necessary.

Hybrid migration is suitable for large organizations that want to maintain coexistence between on-premises Exchange and Microsoft 365. This method allows for a seamless and flexible transition over time.

Steps

   • Set up a hybrid environment using the Hybrid Configuration Wizard.
