Appendix A: Using PowerShell

You can use the On Demand Migration PowerShell API to interact with objects in your On Demand Migration environment. The PowerShell cmdlets allow you to perform tasks, such as account discovery, mail migration, OneDrive migration, task and event management in a PowerShell scripting environment.

The ODM API is available for install or download from the PowerShell Gallery.

NOTE: Usage of the PowerShell Gallery requires the PowerShellGet module to be installed on your computer. The module is normally installed with operating system, but may need an upgrade to the latest version. For more information, see How to Install PowerShellGet.

On Demand User Role Requirements

User must have the Migration Administrator role to access and run any of the On Demand Migration PowerShell commands. On Demand ships with this role. See the On Demand Global Settings Current User Guide for more information about setting up roles.

Deploying the ODM PowerShell API Module

The ODM PowerShell API module must be installed or download from the PowerShell Gallery.

Searching in PowerShell gallery 
Find-Module OdmApi -Repository PSGallery
Installing the module from the PowerShell gallery 
Install-Module OdmApi -Repository PSGallery
Downloading the module from the PowerShell gallery (without installing it) 
Save-Module OdmApi -Repository PSGallery -Path "C:\temp"

Connecting to the ODM service

Before you can use the ODM PowerShell cmdlets to interact with your ODM environment, you must connect and authenticate your access to your ODM host. The credentials you use must be granted a role with sufficient privileges to work with the On Demand Migration services.

Connecting to the ODM service - Interactive mode

The Microsoft Account Authentication Workflow requires user interaction for the initial authentication with Microsoft. When Microsoft Account authentication is used all authentication is handled via Microsoft and the user’s Microsoft Entra ID. This type of authentication supports MFA and is fully controlled by the user’s Microsoft Entra ID Conditional Access Policies. Any password and lockout policies are also managed directly by the customer through their Microsoft Entra ID.

  1. Run the following command to connect to your ODM Service. The default region is US. 
    Connect-OdmService

    To connect to a specific region like Europe, run the command Connect-OdmService -Region EU. The region value can be set in the OdmApi.psm1 file by editing this line: [string]$Region = 'us'. For example to set default region to Europe replace the line to [string]$Region = 'EU'.

  2. This command will redirect the user to the Microsoft Authentication workflow to authentication against the user’s Azure Active Directory. In the authentication dialog, enter the credentials of the On Demand account (not the tenant account)

    If MFA is enforced, users will see an additional window

Connecting to the ODM service - Unattended (or Headless) mode

The Microsoft Account Authentication Workflow requires user interaction for the initial authentication with Microsoft. This type of authentication doe not supports MFA. It is used primary for work or school accounts. The Tenant ID is required.

Connect-OdmService  -Username "admin@democorp.com" -Password "P@ssword!" -TenantId "81f2b32e-c198-44fd-99d4-109665c16f34"

 

Example: Selecting the organization and migration project

Get the organization id
  1. Log in to Quest On Demand.
  2. From the Choose an organization page, note the organization id.

- or, if you have already selected an organization -

  1. Click the logged in user name from the top right corner of the page.
  2. Click the Organization Name from the drop-down to open the Edit Organization page. Then make a note of the organization id.
Connect to the organization

In your PowerShell session console, enter the command:

Select-OdmOrganization -OrganizationId '6a079d6e-e98a-475b-acba-8b08e9caa430'
Select a migration project

Once connected to the Organisation, we need to connect to the Project, the project GUID is required, this is obtained from the ODM GUI or running the command Get-ODMProject which will list all past and present projects associated with the ODM organization, an example of this command is below:

Get-OdmProject | fl
Name                          : New Migration Project
Description                   : Migrate Sales division assets
SourceTenantDefaultDomainName : sourcecorp.onmicrosoft.com
TargetTenantDefaultDomainName : targetcorp.onmicrosoft.com
Id                            : Elf813YBfQYAK6Q42Kun
Connect to your project

Identify the project Id and connect to the project using the following command.

Select-OdmProject 'Elf813YBfQYAK6Q42Kun'

 

Getting Help

OdmApi module supports online help via Get-Help command. Any command syntax and examples of usage can be displayed by the Get-Help command.

Examples:

Get-Help Connect-OdmService

Get-Help Connect-OdmService -Examples

Get-Help Connect-OdmService -Full

 

Appendix B: How Queuing Works

Queuing automates task orchestration and simplifies migration planning. Queuing is used in content migration tasks and allows migration operators to submit migration tasks for many objects at once.

How does queuing work?

When you submit a migration task, On Demand Migration places all objects to be migrated into a queue for that asset, confirms available capacity, and then intelligently selects objects from the queue by processing objects with the highest priority first, using a first-in-first-out approach within that priority.

How do I assign priorities?

When submitting a migration task, you have the option to assign priority levels in the Schedule step of the migration wizard, to help control which objects will be processed from the asset task queue first.

How does first-in-first-out (FIFO) work?

When you submit a new migration task, objects are placed at the end of the asset queue for their assigned priority, meaning that tasks previously submitted with the same priority will be processed first.

As On Demand Migration completes a migration job, it will immediately start processing the next available job by selecting objects from the beginning of the highest priority queue.

This respects the FIFO approach while still ensuring that higher priority tasks are always processed before those with lower priorities.

What is an example scenario?

Let’s imagine that a migration operator submits five OneDrive migration tasks throughout the day, with a mixture of priorities, in the order of Task A, Task B, Task C, Task D, and Task E.

If there is available capacity to process all the objects when each task is submitted, the migrations states of all tasks will immediately switch to Migrating and all five tasks will process concurrently with no queue management required.

However, if the available capacity for OneDrive migrations is at its maximum limit when the tasks are submitted, On Demand Migration will place the objects in the OneDrive queue and then process the tasks in order of priority and FIFO as capacity becomes available.

NOTE: Every On Demand Migration project has its own migration queue and does not compete with asset queues in other projects.

What determines available capacity?

On Demand Migration uses Microsoft APIs to perform migration tasks and must abide by the API limits that Microsoft enforces in each tenant. These limits are in place to ensure that migration activities do not impact your daily business operations. On Demand Migration operates within the available capacity for your source and target tenants.

How do I know which objects are queued?

When you submit a migration task for an asset that is processing at maximum capacity, the newly queued objects will display the migration state Queued in the list view and object detail pane.

You can sort and filter the list view by migration state to view all queued objects.
