Create a Connection

To connect Fly to your source and destination Exchange environments to migrate Exchange On-Premises user/resource/shared/archive mailboxes, you need to add Exchange connections in Fly before the migration.

Refer to the following sections to add Exchange connections.

Create a Source Connection

Refer to the following steps to add source connections:

  1. Click Settings in the left pane, and select Connections to access the Connections page.

  2. Click Create connection. The Create connection panel appears.

  3. In the Create connection panel, complete the following settings:

    • Connection name – Enter a name for the connection.

    • Connection type – Select Exchange On-Premises from the drop-down list to create a source connection for Exchange On-Premises.

    • Credentials – Select an on-premises service account to run the migration jobs (The on-premises service account is created in AvePoint Online Services. Refer to for details.).

      *Note: An on-premises service account must be selected for the Exchange On-Premises. Otherwise, the connection cannot be saved.

      *Note: If you select to create a new on-premises service account in AvePoint Online Services, after you create the service account, click the Refresh (Button: Refresh button.) button to reload the service account.

  4. Click Save to save your configurations.

On the Connections page, you can manage the existing connections.

- Filter – Click **Filter** to filter connections by connection type and/or tenant. - Search – Enter the keyword of a connection name in the search box to search for the desired connection. - Edit – Click the connection name to edit a connection. - Delete – Select a connection and click **Delete** to delete it. You can also select multiple connections and click **Delete** to delete them.

Create a Destination Connection

Refer to the following steps to add destination connections:

  1. Click Settings in the left pane, and select Connections to access the Connections page.

  2. Click Create connection. The Create connection panel appears.

  3. In the Create connection panel, complete the following settings:

    • Connection name – Enter a name for the connection.

    • Connection type – Select Exchange Online from the drop-down list to create a connection for Exchange Online.

    • Tenant – Select a tenant from/to which you want to migrate Exchange Online objects. You can enter the keyword of a tenant in the Search tenant text box and press Enter on the keyboard to search for the tenant.

      If your desired tenant cannot be found from the drop-down list, you need to connect to the tenant in AvePoint Online Services Tenant management. Refer to for details. Then, click the Refresh (Button: Refresh button.) button to reload the tenant.

    • Container for auto map – This setting is unavailable for Exchange On-Premises Migration.

    • Credentials – Refer to the following instructions to configure credentials.

      • App profile – Select an app profile from the drop-down list to use the app profile authentication method to add the connection. You can enter the keyword of an app profile in the Search app profile text box and press Enter on the keyboard to search the app profile.

        • Impersonation user – If you select a custom app profile, the impersonation user you configured in AvePoint Online Services will be automatically filled in. You can change the user to a desired user with the Exchange Online product license assigned in Microsoft 365. This user will be used to identify your Microsoft 365 tenant ID. If the user configured in Fly differs from the one in AvePoint Online Services, the migration will use the user configured in Fly.

      • Service account authentication – Fly provides the following two authentication methods:

        • Legacy authentication – Select a service account from the drop-down list.

          *Note: This method does not support service accounts with multi-factor authentication (MFA) enabled.

        • Modern authentication – If the account has MFA enabled, you can use modern authentication method and select a delegated app profile from the drop-down list to add the connection. You can enter the keyword of a delegated app profile in the Search delegated app profile text box and press Enter on the keyboard to search the delegated app profile.

    • You can also create a new (delegated) app profile or service account in AvePoint Online Services. Remember to click the Refresh (Button: Refresh button.) button to reload the (delegated) app profile or service account after the creation.

      *Note: The service account pool is no longer available in new connections. If you change the option from Yes to No from previous connections, the service account pool section will be hidden when you edit the connection next time.

      *Note: To reduce throttling during migration, we recommend you use the app profile for the migration.
