Gmail (single user mailbox) Considerations

When migrating a single user mailbox to/from Gmail, Transend uses the industry standard OAuth 2.0 protocol, which allows you to authorize Transend software without needing to use a Service Account.

Note: To migrate multiple accounts at once, view instructions to Set up a Google Service Account.

To grant Transend access to migrate a single Gmail user mailbox, follow these steps on the Configure required settings screen:

  1. To begin the authorization process, select the Authorize with Google button to grant access to Transend Migration Console to migrate to/from your Gmail mailbox.

  2. Your default web browser will open to the Google sign-in screen. Select your Gmail account and enter your password (if prompted).

    Alt text

  3. The sign-in screen will state that Transend Migration Console is requesting permission to migrate your email, address book, calendar, and tasks, as well as view your profile.

    Press the Allow button on all 7 screens.

    Alt text

  4. After navigating through all 7 authorization screens, Google will ask you to confirm your choices.

    Press the Allow button to proceed.

  5. You will now be presented with a code. Copy this code:

  6. Paste your code into the Google Logon Result window that Transend Migration Console automatically launched, and click OK:

    Note: this window may be hidden behind other windows you may have open. For easy access, locate the icon on your taskbar.

Once this authorization process is completed, Transend will store in the registry a refresh key that can be used to obtain a temporary data access key. At any time, you can go into the Google dashboard to revoke Transend’s access. You may also revoke access in Transend Migration Console by clicking Revoke Google Authorization.

As long as access is not revoked, Transend Migration Console will be able to perform multiple migrations without further interaction from you, or requiring your password. Transend Migration Console will store refresh keys for multiple users, so as long as you go through the procedure to allow access for each user, you can perform migrations for multiple users.
