- 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, 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 type the following two command lines, and hit Enter each time:
- netdom query fsmo
Step 3. Log in to the target server computer as a member of the local administrator group. And add the Server to the existing domain as a member.
Step 4. Restart the 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 individually 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 this syntax? Check this out:
|This cmdlet will install the domain controller in the active directory infrastructure.
|This parameter can define whether to create DNS delegation referencing active Directory integrated DNS.
|Using this can specify whether the DNS role needs to install with an active directory domain controller. For a new forest, it is the default requirement to set it to $true.
|This parameter defines the FQDN for the active directory domain.
|This parameter can be used to define the active directory site name. The default value is Default-First-Site-Name.
|Using this parameter can define the active directory replication source. By default, it will use any available domain controller. But if needed, we can be specific.
|This parameter will define the folder path to store active directory database file (Ntds. dit).
|A log path can be used to specify the location to save domain log files.
|This is to define the SYSVOL folder path. The default location for it will be C:\Windows
|This parameter will force the command to execute by ignoring the warning. For example, it is typical for the system to pass a warning about best practices and recommendations.
Step 8. Enter a new complex password if the command requests a SafeModeAdministrator Password.
After this, restart the Server system and login as administrator.
Step 9. Open PowerShell again, type Get-Service ads,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 decommission 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 following 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. If you think this guide is complete and valuable, don't forget to share it with others in need.
What Is Active Directory and Why Need to Move It to a New Server
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 include? 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 in the Directory.
- A global catalog - information about every object in the Directory.
- A query and index mechanism - ensure objects and their properties can be published and found by network users or applications.
- A replication service - distributes directory data across a network.
While switching Server computers, one key step is transferring Active Directory to a New Server. Above the page, we've collected two methods that you can follow to successfully migrate the AD database to a new server on your own.
