The Support Options in MigrationWiz offer additional options to make your migration easier and more effective. These are not all available in every project, so each migration type will note which options are most useful to that project.

This article offers guidance on what each Support Option does, as well as how to make best use of them, and which environments they work with.

Use the navigation menu on the side of the screen to navigate to a specific section, or choose ctrl f and enter the copied option from your migration guide or other documentation. 

Support Option Setup

In the Support Options section of MigrationWiz, you can set options for:

• A project, which affects all items in the project.
• A single item, that affects only that item in a project.

Support Options

Each option provides the specific command necessary, the supported environments, the supported migration types, any limitations or important information, and a description. We suggest that these options only be utilized after speaking with a Support agent, as some override existing MigrationWiz settings or permissions. 

Mailbox Migration Support Options

Migrate Suggested Contacts

Option Command: MigrateGmailSuggestedContacts=1

Environment(s) & Scenarios: G Suite

Migration Type(s): Mailbox

Description: Migrates "Other Contacts" in Gmail migrations. If this option is not enabled, these contacts may not migrate. 

Migrate Gmail All Calendar

Option Command: MigrateGmailAllCalendar=1

Migration Type(s): Mailbox migrations

Important: Replace “n” with the new character limit for the request URL.

Option Command: StoreOverflowGooglePropertiesInNotes=1

Environment(s): Google

Migration Type(s): Mailbox migrations

Description: Stores unmappable extra fields (such as extra phone numbers) to contact bodies.

Zimbra Calendar Expand Instances

Option Command: ZimbraCalendarExpandInstances=1

Environment(s): Zimbra

Migration Type(s): Mailbox migrations

Description: Expands calendar instances. This option is useful if Zimbra is missing calendars in the migration.

Recipient Mapping

Option Command: RecipientMapping="@Sourcedomain.onmicrosoft.com->@Destinationdomain.com"

Environments – Source: Exchange 2003+, Microsoft 365, Lotus Notes. Conditionally Supported: Google Apps, Zimbra – calendars support this option for these sources, but mail does not, due to being based on MIME content.

Migration Type(s): Mailbox migrations

Important: The recipient mapping above is only an example: do not copy this verbatim. Change it to reflect your tenant .onmicrosoft.com account name and your customer domain name.

Make sure to click on the "+" sign after entering your recipient mapping. If you do not do this, it will not be added.

Limitations: We do not support recipient mapping for the actual MIME content, so email MIME content-based migrations, such as Zimbra, won't have to remap for email. The MIME content is the information that is listed under Show Details, for a message, for most email systems.

Description: The left part is a RegEx applied to the recipient's email address. You can use more than one remapping expression. This is a very important step for Microsoft 365 to Microsoft 365 migrations. It ensures that emails are replyable to, even after the Full (Delta) Migration has occurred.
