Migration errors

When you run a migration, you might see these errors in the execution log.

Error code Name Description
400 Bad Request There’s data corruption in the source environment. The source data causing the issue is probably defective. You might also see this error when migrating an attachment that is unsupported by Gmail, such as an executable file.

If you want to keep the data, analyze which objects are affected and move them manually to your Google Workspace account. For details on how to manually move objects, consult your source data documentation.

401 Unauthorized Google Workspace Migrate doesn't have the required access to a source or target system.

During a Microsoft Exchange migration, you might see this error:

  • When you try to set up or use a connection—You don’t have permission to impersonate a user on Exchange or your Exchange credentials are expired or incorrect. To fix the problem, edit the connection and make sure the credentials are correct. Then, try the Exchange connection again.
  • In the execution logs for individual users—Usually means impersonation rights granted to an administrator are only valid for a subset of users (for example, a specific organizational unit), instead of all the users that you want to migrate.
403 Forbidden For details about this error, point to the transaction and click Moreand thenTransaction details. Possible causes of this error are:
  • A Google Workspace service (such as Gmail or Google Drive) isn't turned on. In the Google Admin console, turn on the service.
  • You exceeded your daily API quota levels. Apply for a higher quota level in the Google Cloud console. Or, wait until the following day to proceed. Learn more
  • You exceeded a shared drive limit (for example, you might have too many items in a shared drive or exceeded the limits for nested folders). For details, go to Shared drive limits.
409 Conflict Google Workspace Migrate was unable to resolve a conflict with a data source.

If you are running an email migration, the label wasn't created on the target because its name conflicts with an existing label. To resolve the conflict, locate the email folder or label on the source environment and change its name.

410, 5xx Gone Transient errors. Run a delta migration. If the error persists, contact Google Workspace support.
413 Request Entity Too Large

Migrating email messages

An email message and its attachment is larger than 50 MB (maximum size including attachments).

To migrate these messages, use the Upload the attachments of large messages to Drive option in the settings template to send attachments directly to Drive. For details, go to Migrate Exchange content.

Migrating messages to Google Groups

An email message and its attachment is larger than 25 MB. You can't migrate messages over 25 MB to Google Groups. For details, go to Message and posting limits

429 Too Many Requests The migration is overloading a source or target system with too many requests.

Determine which service is overloaded and, if possible, increase the service limits.
