   • Select your current email provider (e.g., Google Workspace, Exchange, IMAP).
3. Configure the Migration:
   • Follow the on-screen prompts to create a migration endpoint.
   • Enter necessary credentials and server settings for your current email service.

   • Provide credentials for both the source and destination email systems.
   • Set up any necessary filters or migration options.

3. Using PowerShell for Hybrid Migration

This method is suitable for environments with existing on-premises Exchange servers.

Step-by-Step Guide:

   • Set up a hybrid configuration between your on-premises Exchange server and Microsoft 365 using the Hybrid Configuration Wizard.
2. Prepare for Migration:
   • Ensure all mailboxes are ready for migration and that there are no outstanding issues.
3. Create Migration Batches:
   • Use PowerShell commands to create migration batches:

     powershell

     Copy code

     New-MigrationBatch -Name "BatchName" -SourceEndpoint "EndpointName" -TargetEndpoint "Microsoft365" -Users "User1, User2"

4. Start the Migration:
   • Start the migration batch using:

     powershell

     Copy code

     Start-MigrationBatch -Identity "BatchName"

5. Monitor the Migration:
   • Monitor the status of the migration batch and troubleshoot any issues using:

     powershell

     Copy code

     Get-MigrationBatch -Identity "BatchName"

6. Complete the Migration:
   • Once migration is complete, finalize the batch:

     powershell

     Copy code

     Complete-MigrationBatch -Identity "BatchName"


4. IMAP Migration

IMAP migration is suitable for migrating emails from non-Exchange servers like Gmail or other IMAP-compatible services.

Step-by-Step Guide:

1. Preparation:
   • Ensure you have the necessary admin credentials and access to both source and destination mailboxes.
