The process to migrate computers from one domain to another via PowerShell is quite complex. Users have to maintain the overall structure of the Active Directory Organizational Unit and align numerous group policies too. Apart from this, as a computer itself has no limit on the number of users, it adds another layer of complexity. 

Therefore, ‌organizations preparing for this task must have a detailed plan with step-by-step instructions. Hence that’s exactly what we deliver here: this blog contains a robust guide with PowerShell commands and their explanations as well. Without further ado, let’s start by discussing the pre-migration steps.

Pre Requisites of A PowerShell Script to Move Multiple Computers to Different Domain

The prerequisites are covered in multiple phases. Be sure not to skip any one of them as it can lead to errors down the line.

Phase 1 Get the Active Directory PowerShell module:

  • Step-1. Use the domain administrator account and log in to the member ‌server.
  • Step-2. Launch a new PowerShell console.
  • Step-3. Type in the following command.
Add-WindowsFeature RSAT-AD-PowerShell 
  • Step-4. Press Enter and wait for the module installation to complete.

Phase 2 – Establish & Verify Trust With The New Domain:

If you add a new domain to an AD Forest it automatically establishes trust with all other domains. However if still in doubt use this command to double-check the trust new domain. Use this command to check if the trust was established or not.

Get-ADTrust -Filter *

Phase 3 – Make a List of All Permissions and Accounts Attached to the Computer(s):

Get all the data regarding the computer’s current settings so it becomes easier to verify and establish it in the new domain. Use the following command:

Get-ADComputerServiceAccount -Identity UserComputerAccount1

Phase 4 – Create a Backup of Current Settings:

Using the checkpoint command you can save a backup of the current computer settings. Moreover, it provides a safety net while attempting to migrate computers from one domain to another using PowerShell. Execute the command given below:

Checkpoint -Computer -Description "DomainChange" -RestorePointType MODIFY_SETTINGS

Explanation:

Description: A mandatory parameter that indicates a user-defined name for a restore point.

RestorePointType: It simply means the type of restore point.

Note: PowerShell commands need to be modified on a case-to-case basis. Avoid direct copypasting, as it may jeopardize data security.

These were just the steps for preparing for the migration. Up next we will cover the Powershell commands for an interdomain computer transfer.

How do I move computers in Active Directory using PowerShell? Explained

For this task, we are going to apply the  Move-ADObject cmdlet. This command can directly move a computer object from one domain to another that exists in a single AD forest.

This operation of moving a computer between Active Directory domains requires users to specify both source and target domains. They should also have preestablished mutual trust.

Apart from this, the source and target DC also need the owner’s role in the domains of  RID Master FSMO. Below is an example of moving the computer between AD domains.

Get-ADComputer -Identity UserPC | ` 
Move-ADObject ` 
-TargetPath "OU=Computers, DC=TargetDomain, DC=tld" ` 
-TargetServer "TargetDC.TargetDomain.tld " ` 
-Server "SourceDC.SourceDomain.tld"

In case your organization does not use the default AD format the above-mentioned command may fail to deliver results. 

An alternative way to use a custom PowerShell script to move multiple computers to different domains is to create a function. Here is a template that you can utilize. Please make the necessary changes to migrate computers from one domain to another via PowerShell for the best results.

function domain_move($compacc,$fqdn) {
$username_joinTarget=”DestinationDomain\DestinationServiceAccnt”
$password_joinTarget=cat“d:\scripts\server_move\AttachTarget.txt”|convertto-securestring
$cred_JoinTarget=new-object -typename System.Management.Automation.PSCredential –argumentlist $username_joinTarget,$password_joinTarget
$username_unjoinSource=”OriginDomain\OriginServiceAccnt”
$password_unjoinSource=cat“d:\scripts\server_move\RemoveSource.txt”|convertto-securestring
$cred_UnjoinSource=new-object -typename System.Management.Automation.PSCredential -argumentlist $username_unjoinSource,$password_unjoinSource
$Error.clear
Try {Add-Computer -ComputerName $compacc -DomainName $DestinationDomain -Credential $cred_AttachTarget -UnjoinDomainCredential $cred_RemoveSource -Server $TargetDC -PassThru -Verbose}
Catch {return $false}
Start-Sleep -Seconds 15
Restart-Computer -ComputerName $fqdn
return $true}

Moreover, the software completely eliminates the risk of data loss that comes with using PowerShell commands. Apart from this, it is incredibly easy to use. Here is a list of steps to follow.

Step-1. Launch the tool, and type “administrator” in place of both the user ID and password.

Enter Default Credentials

Step-2. Press “Register Domain Controller”, type name, IP then click on “Save & Continue”.

Register Domain Controller for Source

Step-3. Repeat the same step for the destination domain and proceed further.

repeat for target

Step-4. Click on the source domain, enter the admin credentials, then hit “Save & Continue”.

Add and Validate Admin Credential

Step-5. Go to the Active Directory section, and press “Fetch Active Directory Objects”.Fetch Active Directory Objects

Step-6. Repeat the same step for the destination domain and proceed further.

Repeat For Target

Step-7. Create Migration Scenario in Migration Section, enter the name, and select source & target.

Step-8. Create a new task, pick the computer as workload, & hit the “Save & Continue” button.

Create New Task (Select Computers)

Step-9. When all chosen objects are visible click on the (…) to either create or merge. 

Click on (...)

Step-10. Once the mapping completes, hit the start task, then press start in the pop-up box. Either Merge or Create

Step-11. After migration, the tool can generate a domain-wise or migration-wise report.
