Hello all,
We got one requirement from the customer.
They will implement a new Domain controller and a new forest.
Existing information: OLD-AD01 (OS Win. 2003)
OLD-SQL1 (OS Win. 2016)
OLD-SQL2 (OS Win. 2016)

New Domain controller 2019.

We want to join the existing SQL cluster to a new domain.

Could you advise the procedure?

    Hi chindasam-5378,

    Welcome to Microsoft Q&A.
    SQL Server cluster is based on Windows server cluster. In Windows Server 2016 and earlier, the Cluster service didn't have the capability of moving from one domain to another. This was due to the increased dependence on Active Directory Domain Services and the virtual names created.
    There are two options to do such a move. The first option involves destroying the cluster and rebuilding it in the new domain. The second option is less destructive but requires additional hardware as a new cluster would need to be built in the new domain. Once the cluster is in the new domain, run the Cluster Migration Wizard to migrate the resources.
    Please refer to this doc for more information.

    Best Regards,
