Steps to Migrate IMAP to Microsoft 365

Date Filter Option is available in this tool to migrate only selective data from Source IMAP Server to Office 365.

Here, for example, we are selecting G Suite as our source IMAP server.

Enter the Destination Admin Email and Application ID & then click on the Validate button to validate all permission.

Once the permissions are Validated. Click on Next button.

In the Users screen, there are two ways in which you can add users from the source account that needs to be migrated.

Users can also filter out the selected users for migration and also allocate Priority if they have multiple user mailboxes and want to migrate some of them prior to others. Following that, click on the Start Migration button located at the top right corner.

You'll get a prompt screen saying "Migration Started Successfully".

Users can also Stop Migration if required while the migration is In Progress.
