Step 1: On the Source Google Workspace Side

• An active Google Workspace admin account with Super Administrator privileges.
• API access is enabled in the Google Workspace Admin console.
• Service account with domain-wide delegation configured for secure mailbox access.

• If migrating multiple mailboxes, prepare a CSV file with columns such as email address, password, IMAP server host name, and port number.
• If you are migrating to a Gmail account, ensure that you create an App Password for the Gmail account.

Follow these steps to securely migrate your mailboxes from Google Workspace to any IMAP server using EdbMails:

• Step 1: Download the EdbMails Application

  • Download and install the EdbMails application on your computer.

      See the EdbMails system requirements for Google Workspace migration.

    

  • Enter your registered email address and password, then click ‘Login’. If you don’t have an account yet, select ‘Start Your Free Trial’ to access the trial version.

    

  • Select the option ‘Google Workspace Migration’.

    

  • Select ‘Google Workspace to IMAP Migration’.

    

  • You may continue with the default job name, or click ‘New Job’ to create and assign a custom name of your choice.

    

• Step 2: Connect to Source Google Workspace Server

  • Enter the ‘admin email address’, click ‘Browse’ to select the JSON file you downloaded from the Google Cloud Console, and then click the ‘Login’ button.

  • Select one of the methods to load the mailboxes, then click ‘Next’.

    

  • Select the mailboxes you want to migrate, then click ‘Next’ to continue.

    

• Step 3: Connect to the target IMAP server

  • To connect a single user account, select ‘Single User / Account Migration’. Then choose the required protocol, such as ‘Connect to IMAP Server’ or ‘Connect to POP3 Server’, and click ‘Next’ to continue.

    

  • Select the appropriate ‘IMAP host name’ from the list, or enter it manually. Then provide the ‘email address’ and ‘password’. For Gmail accounts, generate an app password and use it instead of your regular account password.
  • Click the ‘Login’ button.

    

  • Once the mailboxes are loaded, click ‘Next’ to proceed.

    

  • To migrate multiple mailboxes, select ‘Multiple (Bulk) Users/Accounts Migration’, then click ‘Next’ to continue.

    

  • Click ‘IMAP Migration CSV File’. You will be prompted to download a sample.csv file. Select the destination folder where you would like to save the file.

    

  • Open the downloaded CSV file and update it with the required details, including the email address (mailbox name), password, host name, and port number. You may enter ‘NA’ in the remaining fields, as they are not required for email migration. After completing the updates, save and close the CSV file.

    

  • Click ‘Load Modified CSV File’ to select the updated CSV file, verify the listed mailboxes, and then click ‘Next’ to proceed.

    

      Refer to the EdbMails guide for detailed steps on connecting both single and multiple user accounts during IMAP migration.

• Step 4: Map Source and Target Mailboxes

  • Choose the required mailbox mapping option.

    

  • EdbMails automatically maps source and target mailboxes. You can also manually map the mailboxes.

    

• Step 5: Start Google Workspace to IMAP Migration

  • Click the ‘Start Migration’ button and initiate the migration process.

    

  • Click ‘View Logs’ to access the migration report, which provides a detailed summary of the emails, folders, and mailbox items migrated, along with their respective counts.

    

After completing the migration from Google Workspace to your IMAP server using EdbMails, perform the following tasks to ensure everything is working correctly:

1. Verify Mailboxes

Check that all emails, attachments, and folder structures have been migrated successfully to the target IMAP server.

2. Check Folder Hierarchy

Ensure that the original folder structure from Google Workspace is preserved.

3. Test Mail Flow

Send and receive emails from the migrated mailboxes to confirm that they are functioning properly.

4. Run Incremental Migration if Needed:

If new emails arrived in Google Workspace during the migration, you can use EdbMails’ incremental migration feature to transfer only the new items.
