Quest recently announced that the On Demand Migration (ODM) PowerShell API module is now available in the PowerShell gallery. To help get you started, we have compiled a few example scripts that demonstrate how to perform common migration activities using the ODM API.

The examples below assume you have already connected to ODM and selected your Organization, Project, and ProjectWorkload, as described in the ODM API New Feature Spotlight.  Note that these scripts are provided as-is for example purposes only, and you may need to modify them to work for your specific project.

Discover Accounts - Create task, start task, monitor task status

This example demonstrates how to create a task to discover all accounts, start the task and monitor the status of the task until it is no longer In Progress.

#  Discover objects in Accounts Project #
#########################################
$SleepMinute = 1 # Defines the wait time in minutes between querying the task status 
$TaskName = "Discover All Objects"

# Defines the tasks settings
$ACCDiscoverParam = @{Name        = $Taskname
    DiscoverUsingCSV              = $false
    FilePath                      = $null
    DiscoverUsingGroups           = $false
    DiscoveryGroupsFilePath       = $null
    CreateApplicationAccessPolicy = $false
    NotifyOnTaskCompletion        = $true
    NotifyOnlyOnTaskFailure       = $false
    NotificationRecipientEmail    = "example@domain.com"
    ScheduledStartTime            = $null
}

# Create the task
$Task = New-OdmDiscoveryTask @ACCDiscoverParam
# Run the task
Start-OdmTask $Task

# Monitor task until no longer In Progress
Do {
    Clear-Host
    $Running = Get-OdmTask -All -TaskId $Task.Id
    $Running | Sort-Object Name | Select-Object Name, Progress, Status | Format-Table *
    If ($Running.Status -eq "In Progress") { Start-Sleep ($SleepMinute * 60) }
}While ($Running.Status -eq "In Progress")

Migrate Accounts - Create multiple tasks with a defined number of objects

This example demonstrates how to create multiple tasks with the defined number of objects. For example, if you need to migrate 2000 accounts, you can split the migration into 10 tasks with 200 accounts each. Note: This example creates the tasks, but does not run them. 

# Create task(s) for migrating user accounts #
#############################################
# The below script will create tasks based on the setting in NumberOfObjects variable.
# Using Type to filter for User objects only.

$TaskName = "Migrate User Accounts"
$NumberOfObjects = 50 # Defines the number of accounts added to a single task

# Download every object from project
$AllObjects = Get-OdmObject -All
Write-Host "All Objects count:"$AllObjects.Count
# Filter for objects where the Type is User
$Objects = $AllObjects | Where-Object { $_.Type -eq "User" }
Write-Host "Available Objects to create task count:"$Objects.Count
$SegmentCount = 1; $SegmentStart = 0
# Calculate how many tasks will be created
$WillCreate = [math]::ceiling($Objects.Count / $NumberOfObjects)

Do {
    $Objects2Add = $Objects | Select-Object -Skip $SegmentStart -First $NumberOfObjects
    $CurrTaskName = ($TaskName + " " + $SegmentCount + " / " + $WillCreate)
    Write-Host $SegmentCount" / "$WillCreate
    # Defines the tasks settings
    $ACCMigParam = @{Name          = $CurrTaskName
        TargetUpnSuffix            = $null
        CustomForwardingDomain     = $null
        SendInvitation             = $true
        InviteRedirectUrl          = $null
        NotifyOnTaskCompletion     = $true
        NotifyOnlyOnTaskFailure    = $false
        NotificationRecipientEmail = "example@domain.com"
        ScheduledStartTime         = $null
    }

    # Create task
    $CurrTask = New-OdmMigrationTask @ACCMigParam
    # Adding the defined number of accounts to the task
    $CurrTask | Add-OdmObject -object $Objects2Add
    $SegmentStart = $SegmentStart + $NumberOfObjects
    $SegmentCount = $SegmentCount + 1
}While ($Objects.Count -gt $SegmentStart)

Migrate Mailboxes - Create task from collection, schedule task start time

This example script demonstrates how to create a task from a collection and schedule the task to start after a defined number of minutes.

# Create task for Migrating mailbox(es) from a Collection #
#######################################################
# Create and start a mailbox migration task based on Collection members and schedule the start

Monitor Tasks - Return status and details for In Progress tasks

This example script demonstrates how to monitor running tasks and return detailed info, utilizing filters such as Wildcardfilter, tasktype filters, and Get-OdmEvent filters.

# Monitor In Progress tasks #

Auto Start Tasks - Auto-start tasks, limit number of concurrent parallel tasks

This example script demonstrates how to automatically start tasks based on how many parallel tasks you want to run for a specific task type.

# Automatically Start New tasks #
