Remediation

Outline

Cloned Databases are read only.

When we upgraded our SQL Server Instance from v2016 to v2017, read only databases such as cloned databases are skipped.

All other databases are brought up to the version of the SQL Server Instance.

If we really do need a cloned database, we will create it.

Create Cloned Database

SQL

DBCC CLONEDATABASE 

    (
          [WideWorldImportersDW]
        , [WideWorldImportersDW_DBCCClone_v2017]
    );   

GO
