What's new in GAMME

As we add features, enhancements, and fixes to Google Apps Migration for Microsoft® Exchange (GAMME), we'll regularly update this page. Download the latest version of GAMME from the download page. To learn more about the migration tool, see Overview: Google Apps Migration for Microsoft Exchange.

Important Upgrade

If you are running a previous version of GAMME you must upgrade to GAMME 4.1.

This upgrade is required because all previous versions of GAMME used the Google Apps Provisioning API and Email Migration API v1, which have been deprecated and stopped functioning on April 20, 2015.

When upgrading to GAMME 4.1, the OAuth API scopes required have changed to support the new APIs. Please review the Google Apps Migration for Microsoft® Exchange Admin Guide for steps on setting the proper API scopes.

Release 4.4.2166.1322
April 28, 2015

What's Fixed

Running GAMME from the command line against an IMAP source using --nouse_gui with start and end date parameters was not being properly honored. Message content outside of the date range was being migrated. Content outside the date range is no longer incorrectly migrated.

Release 4.3.2132.1410
March 24, 2015

What's Fixed

Deleted items were being migrated into the Gmail inbox and not trash. Deleted items now are properly migrated to trash.

Changed the required minimum wait between email migration API requests from 700ms to 1000ms.

Release 4.2.2122.753
March 11, 2015

What's Fixed

GAMME now properly includes the project key with each request to fully account for EMAPI API quota. This fix prevents future issues that may occur if the API quota limits are exhausted.

Release 4.1.2089.1157
February 17, 2015

What's New

New APIs

GAMME email migrations now uses the latest Email Migration API (version 2).

GAMME now uses latest Directory API (version 1) for user validation.

Vault migrations

GAMME Vault migrations now strip user labels by default. Administrators no longer need to specify the
--strip_user_labels option.

Blocked content can be written to mbox file

Where some file types are blocked and can't be migrated due to file size or type, the administrator can choose to have the message content written to a user-specific mbox file.

What's Fixed

The command line option --strip_user_labels is now showing in the command line --help details.

The command line option --migrate_to_vault is now showing in the command line --help details. It is now no longer ignored when using the GUI to perform the migration.

Release 4.0.1816.543
May 29, 2014

What's New

Outlook 2013 is now supported (not including Click-to-Run editions).

What's Fixed

This release fixes the following issues:

  • GAMME no longer crashes during IMAP migrations if some messages can't be downloaded from the IMAP server.
  • GAMME no longer crashes while loading the folder hierarchy in some Exchange/PST migrations.
  • The help tooltips' content was updated and some broken Learn more links fixed.
  • GAMME can now get the sender's email address from the message's internet headers even if it's missing from the sender field in Outlook.
  • GAMME no longer crashes when migrating multiple PSTs for the same user.
  • Running an IMAP migration from the command line no longer fails to start with an error about missing command line flags.
  • The command line flag trace in the GAMME logs is no longer truncated.
  • Calendar migrations now recognize more timezones.
  • The migration no longer fails to migrate some folders due to reaching the label creation rate limit of the Email Settings API. Label creation is now retried up to 10 times.
  • Project IDs created using the Google Developers Console can now be used as consumer key and consumer secret for migrations. See Use a Developers Console API project for the migration for more information.
  • Some events would fail with error 0x80040304 during Calendar migrations - this is now fixed.
  • Some textual corrections.
