This topic describes how to set up the On Demand Migration Domain Move Project, how to deploy the Directory Sync Agent and how to configure the Directory Sync Integration. 

On Demand Project

This section explains how to add a Microsoft 365 tenant and configure a Migration project using On Demand Migration. During project setup an Office 365 Global Administrator account is initially required to add each tenant to the project.

  1. Log in to On Demand

  2. Navigate to Tenants

  3. Choose the Add Tenant button

  4. On Demand supports both Commercial and GCC High tenants, for the purpose of this guide, select Commerical Tenant, and choose Add Commerical or GCC Tenant and choose OK.

  5. Log in to Office 365 with a Global Administrator account for the source tenant.

  6. Accept the requested Application Permissions

Setting up the Domain Move Project

Follow these steps to setup the Domain Move Project.

  1. Log in to On Demand

  2. Navigate to Migration

  3. Select an existing migration project

  4. Click on Domain Move from the Project Dashboard

  5. Once the On Demand Migration Active Directory module is loaded, click on the Domain Move icon in the main dash view.

  6. Click the New Project button and bring up the project setup wizard

  8. Click on the New button to create a new environment or choose any existing environments from the list. Click Next once you have at least two environments selected.

  9. Choose the source and target environments from the dropdown menu and click Next.

  10. Configure the domain mapping for your project and click Next.

LightbulbImportant Tip: Domain Mapping will be used to match objects and allows On Demand Migration Active Directory to add the source domain to all matched target objects during the domain move.

  1. Configure the attributes to use to match users and groups. Once complete, click Next

LightbulbImportant Tip: Multiple attributes can be selected and On Demand Migration will evaluate each one until it finds a matching source and target object.  If more than one attribute is selected, the first attribute that matches is used.

  1. Copy the Directory Sync agent Registration URL and Registration Key and click Next. NOTE: this information can be obtained again after the project is configured.

  2. On Demand Migration for Active Directory offers two email relay service modes.  For the purpose of this guide, select Advanced Mode and click Next.

  3. Upload a SSL Certificate for each environment.  On Demand Migration for Active Directory will ensure mail delivered during a domain move is always encrypted, secure and private by using this SSL Certificate.  Click Next once the certificates are uploaded.

LightbulbImportant Tip: A single subject certificate with both private and public key must be used.

  1. Review the project configuration settings and click Next

  2. Enter an email address and click on Start Discovery to finish the project setup

LightbulbImportant Tip: Domain Move projects will not create any objects in the source or target Active Directory; it simply requires this OU information to complete the project setup.  We plan to make this step optional in a future release.

Validating Object Matches

This section provides a step-by-step guide on how to validate object matching.

  1. Log in to On Demand

  2. Navigate to Migration, select the project and click on Domain Move.

  7. Repeat step 10 - 12 for Groups.

If the Domain Move project is unable to automatically match the users by attributes, you can upload a user list to be used as a mapping file. This process will only update the users found in the file and will not impact any other users in your project.

Uploading a CSV for User Matching

  1. Click Update to open the CSV upload wizard.
