There are some requirements that I have not added to this article; you can find them in Microsoft articles.
I will run the commands in a domain member machine, not in the domain controller. In the domain member server:
>Install-WindowsFeature RSAT-AD-Tools -IncludeAllSubFeature
In the domain controller create a DNS zone for your new domain:
OLD Domain: contoso.com
New Domain: contosonew.com
>Add-DnsServerPrimaryZone -Name contosonew.com -ReplicationScope "Domain" –PassThru
In the domain member-run:
>rendom /list
A Domainlist.xml will be created. You need to edit the file and replace the DNSname and NetBiosName
<?xml version ="1.0"?>
<Forest>
<Domain>
<!-- PartitionType:Application -->
<Guid>891277a0-70de-4f9d-a176-80140ea9c334</Guid>
<DNSname>ForestDnsZones.contosonew.com</DNSname>
<NetBiosName></NetBiosName>
<DcName></DcName>
</Domain>
<Domain>
<!-- PartitionType:Application -->
<Guid>e60931a4-f3e9-4b7c-8ae2-1e4d2078338c</Guid>
<DNSname>DomainDnsZones.contosonew.com</DNSname>
<NetBiosName></NetBiosName>
<DcName></DcName>
</Domain>
<Domain>
<!-- ForestRoot -->
<Guid>e070ac56-99c0-4005-8193-40535c6eabd1</Guid>
<DNSname>contosonew.com</DNSname>
<NetBiosName>CONTOSO</NetBiosName>
<DcName></DcName>
</Domain>
</Forest>
>rendom /showforest
Upload the file:
>rendom /upload
Prepare:
>rendom /prepare
Execute, Domain Controllers will be restarted automatically
>rendom /execute
Fix the GPO issues in the domain controller:
gpfixup /olddns:contoso.com /newdns:contosonew.com
gpfixup /oldnb:TEST /newnb:RESOURCE
Rename the Domain Controllers:
netdom computername DC1.contoso.com /add:DC1.contosonew.com
netdom computername DC1.contosonew.com /makeprimary:DC1.contosonew.com
Remove the old reference to the old domain
rendom /clean
Finish the process (For me I got several error, and after a few minutes and was able to finish the process):
rendom /end
