How to exclude data

Specify a migration start date

If you don't want to migrate old email or calendar events, specify a start date for the migration. Any email or calendar events older than the start date won't be migrated. The data migration service migrates email or calendar events from the start date to the current day, starting with the most recent email. 

 In the Migration start date section, choose an option to specify a start date:

  • Select a given period of time.
  • Select Custom date and choose the date of the earliest email or calendar event you want to migrate.
Choose to not migrate deleted or junk email

If you don't want to migrate deleted or junk email, uncheck the following boxes in the Migration options section:

  • Migrate deleted email
  • Migrate junk email
Specify folders that don't need to be migrated

You might have some folders (for example, sent mail) that don't need to be migrated. Or, your users may have personal email messages that shouldn't be moved to the new G Suite account. Before you begin the migration, put the items into a top-level folder. You can create more than one top-level folder. During the migration, you specify the folders in the Migration options section so you can exclude them.

Tip: A top-level folder is a folder at the same level as the Inbox. To keep it simple, use a naming convention, such as "MyFolder”, to make the folders easier to identify.

To exclude specific top-level folders with the data migration service: 

  1. Check the Exclude the following top-level folders from migration box. 
  2. Specify the folders in a comma-separated list (for example, Sent Items,MyFolder).

    Make sure the folder name in the list is exactly the same as the name in your mail service—has the same capitalization, spacing, and so on.

Choose to not migrate certain Gmail labels

If you are migrating from a G Suite account and you don't want to migrate specific Gmail labels:

  1. Check the Exclude the following top-level folders from migration box. 
  2. Specify the labels in a comma-separated list.

    Important: You must also add All Mail to the comma-separated list. If you don't, messages from the excluded label that also have the All Mail label will be migrated.

Choose to not migrate secondary calendars

If you don't want to migrate secondary calendars, uncheck the Migrate secondary calendars box.
