How Do I Migrate or Transfer Active Directory (AD) to Another Server
"Does anyone know how to transfer Active Directory to another Windows Server computer? For example, I purchased a new Windows Server 2022, and I want to move AD from my old Windows Server 2016 to Server 2022. How do I do it?"
Are you looking for a reliable way to migrate the Active Directory database from a Windows Server computer to a new Server machine? Relax, and don't worry if you are a new Server manager. Here on this page, we'll show you the complete procedure of successfully migrating AD from Server to Server. First, let's see the details:
In this article, you'll learn:
- What Is Active Directory and Why Need to Move It to a New Server
- Method 1. Backup Active Directory and Restore It to Another Server
- Method 2. Use Active Directory Migration Tool
Before migrating AD to a new Server, let's see what Active Directory is and why it's so important that Windows Server users want to transfer it from Server to Server.
What Is Active Directory and Why Need to Move It to a New Server
- By Microsoft Active Directory Overview
According to the above description, an Active Directory can be regarded as a database called AD, which connects users to network resources to accomplish their tasks. So what does Active Directory includes? Check this out:
- Information objects - shared resources such as servers, volumes, printers, network users, and computer accounts.
- A set of rules - schema defines the classes of objects and attributes contained in the Directory.
- A global catalog - information about every object in the Directory.
- A query and index mechanism - make sure objects, and their properties can be published and found by network users or applications.
- A replication service - distribute directory data across a network.
While switching Server computers, one of the key steps is to transfer Active Directory to a New Server. Here following, we've collected two methods that you can follow to successfully migrate the AD database to a new server on your own.
Both methods work to transfer Active Directory from one Server to another Server on Windows Server 2022/2019/2016/2012 r2/2012/2008 r2/2008/2003, etc.
Method 1. Backup Active Directory and Restore It to Another Server
- Tool: PowerShell
- Difficulty Level: high
Suppose you've got two Windows Server computers, and now you are about to transfer the active directory database from one Server to another Server computer. Here are the manual steps that you can follow:
Step 1. Introduce a new domain controller with the target Server to be the new FSMO role holder for the domain.
To migrate the FSMO role, you can refer to this post in the Microsoft community for help: Transfer FSMO Roles in Active Directory.
Step 2. Introduce new domain controllers to the forest root and domain tree levels.
Open PowerShell and type the following two command lines and hit Enter each time:
- netdom query fsmo
Step 3. Login into the target Server computer as a member of the local administrator group. And add Server to the existing domain as a member.
Step 4. Restart Windows Server and logo into the Server as Enterprise Administrator.
And assign the static IP address to the Server.
Step 5. Right-click the Windows icon and select "Windows PowerShell (Admin)".
Step 6. Type Install-WindowsFeature –Name AD-Domain-Services -IncludeManagementTools in PowerShell and hit enter.
This will install the Active Directory Domain Service Role in the given Server.
Step 7. Type the following syntax command lines one by one and hit Enter each time in PowerShell. This will configure the new Server as an additional domain controller:
- -DomainName "rebeladmin.net"
- -SiteName "Default-First-Site-Name"
- -ReplicationSourceDC "DC08.rebeladmin.net"
- -DatabasePath "C:\Windows\NTDS"
- -LogPath "C:\Windows\NTDS"
- -SysvolPath "C:\Windows\SYSVOL"
There are no line breaks for the command listed above. So what are the meanings of these syntax? Check this out:
|Install-ADDSDomainController||This cmdlet will install the domain controller in the active directory infrastructure.|
|-CreateDnsDelegation||Using this parameter can define whether to create DNS delegation that reference active directory integrated DNS.|
|-InstallDns||Using this can specify whether DNS role need to install with active directory domain controller. For new forest, it is default requirement to set it to $true.|
|-DomainName||This parameter defines the FQDN for the active directory domain.|
|-SiteName||This parameter can use to define the active directory site name. the default value is Default-First-Site-Name.|
|-ReplicationSourceDC||Using this parameter can define the active directory replication source. By default, it will use any available domain controller. But if need we can be specific.|
|-DatabasePath||This parameter will use to define the folder path to store active directory database file (Ntds.dit).|
|-LogPath||Log path can use to specify the location to save domain log files.|
|-SysvolPath||This is to define the SYSVOL folder path. The default location for it will be C:\Windows|
|-Force||This parameter will force the command to execute by ignoring the warning. For example, it is typical for the system to pass the warning about best practices and recommendations.|
Step 8. Enter a new complex password if the command requests for SafeModeAdministrator Password.
After this, restart the Server system and log in as administrator.
Step 9. Open PowerShell again, type Get-Service adws,kdc,netlogon,dns and hit Enter to check the AD DS status.
Step 10. Type Get-ADDomainController -Filter * | Format-Table Name, IPv4Address, Site in PowerShell, and hit Enter.
Step 11. Migrate all FSMO roles to the new domain controller by typing Move-ADDirectoryServerOperationMasterRole -Identity REBEL-DC2019 -OperationMasterRole SchemaMaster, DomainNamingMaster, PDCEmulator, RIDMaster, InfrastructureMaster in PowerShell and hit Enter.
Note: Replace REBEL_DC2019 with your new running Windows Server.
Step 12. Type Netdom query fsmo in PowerShell to verify the new FSMO role holder.
Step 13. Type Uninstall-ADDSDomainController -DemoteOperationMasterRole -RemoveApplicationPartition to decomission the old Windows domain controller.
Step 14. Type Set-ADDomainMode –identity therebeladmin.com -DomainMode Windows2016Domain in PowerShell and hit Enter to upgrade the functional domain levels.
Step 15. Type Set-ADForestMode -Identity therebeladmin.com -ForestMode Windows2016Forest in PowerShell and hit Enter to upgrade forest functional levels.
Wait for the process to complete. After this, the Server AD migration process completes. You can then verify if it completes successfully by typing the next two command lines in PowerShell and hitting Enter each time:
- Get-ADDomain | fl Name,DomainMode
- Get-ADForest | fl Name,ForestMode
As shown above, if you see the result, you've successfully transferred Active Directory to a new Server machine.
