What is migrated?

Google Workspace Migration for Microsoft Exchange (GWMME) migrates email, calendar, or contact data from Microsoft Exchange, an IMAP server, or a PST file to your Google Workspace account. Consider the following data and whether it's migrated, when you're setting up a migration to Google Workspace with GWMME.

Email

Supported email features	Notes
Email messages	All email messages in top-level folders are migrated. A top-level folder is any folder that is at the same level as your inbox folder. You can also choose to migrate email to Google Vault.
Email state, such as read or unread
Deleted items	Migration is optional. Deleted items are labeled Trash in Gmail.
Folders	Folders map to labels in Gmail. You can exclude specific top-level folders from a migration by individually selecting them. If you exclude a folder, its subfolders are also excluded. Folders with folder paths longer than 225 characters aren’t migrated. The messages inside the folders are also not migrated. When you set up your migration, you can exclude specific top-level folders. For details, go to Chapter 6 of the GWMME Admin Guide.
Junk email	Migration is optional. Junk email is labeled Spam in Gmail.
Public folders	You can migrate content from public folders to Google Groups. For details, go to Migrate from public folders.
Large messages & attachments	Most attachments are migrated, except when the message plus attachment is larger than 25 MB, or when Gmail blocks certain types of file attachments, such as executable files. For details, go to File types blocked in Gmail.
Message flags	Flags appear as stars in Gmail.
Shared mailboxes	Shared mailboxes migrate as regular mailboxes. You can turn on Gmail delegation after the migration. For details, go to Turn Gmail delegation on or off.
Subfolders	How a subfolder migrates depends on its location: Subfolder in a default folder—If the subfolder is under an Exchange mailbox default folder (such as Sent Items, Drafts, or Deleted Items), the subfolder doesn’t migrate as a nested label. Instead, it’s nested under the default folder name preceded by an underscore (for example, _Inbox/Financial). Subfolder under other folders—Migrates in a nested state (for example, Financial/Q1 Invoices).

 

Unsupported email features	Notes
Posts in mailbox folders
Importance levels of messages
Rules	Rules (both server and client) aren’t migrated but you can create equivalent filters in Gmail.
Signatures	Signatures aren’t migrated but you can recreate them in Gmail.
Category definitions or assignments

Calendar

Supported calendar features	Notes
Default calendar, including events, descriptions, attendees, event reminders, and locations	If you’re using an exported or archived PST file, all calendars are migrated as Other calendars instead of as the default calendar. You can avoid this by using an Exchange server migration for importing calendars. For details, go to Migrate data from Exchange.
Calendar events	A warning message appears in the log file if you import events for users who aren’t the original organizer or initial attendee for the event. However, the event successfully migrates and the target user is shown as an attendee of the event in Calendar.
Other calendars	Other calendars are migrated for the owner, but not for other users who have access.
Free or busy status
Calendar resources	Use a comma-separated value (CSV) file to migrate calendar resources (such as meeting rooms). You can also use the file to change event attendees' email addresses to Gmail email addresses. For details, go to Create CSV files for your migration.

 

Unsupported calendar features	Notes
Rich content in event descriptions	Rich text descriptions aren't imported. In Microsoft Outlook 2016, descriptions are converted to plain text.
Tentative or Out of Office status	Any special status for calendar data is not migrated.
Calendar attachments
Category definitions or assignments

Contacts

Supported contacts features	Notes
Personal contacts	Includes all fields
Notes	Notes in contacts are migrated as plain text. Notes larger than 16 KB are truncated.

 

Unsupported contacts features	Notes
Contact folders	Separate contact folders don’t migrate. Instead, all contacts from all folders are migrated. You can reorganize them using labels.
Contact groups or personal distribution lists	Contact groups or personal distribution lists don’t migrate. You can send an email to a list from Google Workspace by creating a group using the Admin console.
Global domain contacts	Domain contacts appear in the Global Address List (GAL) in Microsoft Active Directory. To import these contacts, you must use a different product. For details, go to About Google Cloud Directory Sync.
