Google Workspace / Gmail Considerations
To migrate bulk accounts to or from Google Workspace/Gmail (formerly called G Suite) without end-user passwords (admin authentication), you will need to set up a Google Service Account.
You will grant permission to a service account to access your Google Workspace data. In most cases this will be a service account created by you.
Note: To migrate a single mailbox (or a few mailboxes) without usage of a Service Account, view instructions to migrate individual accounts with end-user authentication.
Google Service Account
To create a Google service account, perform the following steps:
In the Google Cloud Platform Create a project
Click CREATE PROJECT on the right side of the screen.
Assign a Project Name, an (optional) Organization and then click CREATE.
To Enable Access to APIs, Confirm project by selecting NEXT
Enable APIs by clicking ENABLE
When you see all APIs have been enabled (displayed with a checkmark) click the link at the bottom
Select the Project you just created, which by default will be called My Project unless you assigned it a name
Click + CREATE SERVICE ACCOUNT at the top of the screen
In the Service account name field, enter Transend as the name and then click DONE
Click your Service Account’s email address
Click the Keys tab at the top
Click Add Key > Create new key
Change to P12 key and click CREATE
The .p12 key is downloaded to your Downloads folder
Copy the .p12 key to the following directory:
c:\ProgramData\Transend
Click the Details tab at the top and copy the service account email address and Unique ID into notepad
Open the Google Admin Console
Click Security > Access and data control > API controls
Click MANAGE DOMAIN WIDE DELEGATION
Click Add new at the top of the screen
In the Client ID field, paste in the Unique ID that you previously copied into NotePad
OAUTH Scopes:
Highlight the below scopes and click Ctrl-C to copy the scopes into Notepad, into a single line comma delimited. Then paste it into the OAUTH Scopes field.
Important: To maintain proper encoding you must use Ctrl-C when copying scopes. If you right click to copy you will lose important characters like commas and colons.
Click Authorize
Enter credentials into Transend Migration Console
Enter the following Service Account credentials into Transend Migration Console on the Configuration Settings > Required screen:
Service account email address – this is the service account email address you copied to notepad in step 16
