    We can move the site database to a new instance of SQL Server on the same computer, or to a different computer that runs a supported version of SQL Server.
    Run Configuration Manager setup on the site server, and select the option Perform site maintenance or reset this site. Then select the Modify SQL Server configuration option. Then we can change instance of SQL Server.
    Note when we move the database to a new instance on SQL Server, we need to enable common language runtime (CLR) integration. Use SQL Server Management Studio to connect to the instance of SQL Server that hosts the site database. Then run the following stored procedure as a query: sp_configure 'clr enabled',1; reconfigure

    Here is the documentation and the precautions:

    Hi Allen and Jason

    Thanks for your help

    I followed the steps to move to CM database from default instance to another instance (Always On)

    when I try to modify SQL configuration using SCCM setup wizard which is located in cd.latest, I get the below errors

    ERROR: SQL Server error: [08001][-2146893019][Microsoft][SQL Server Native Client 11.0]SSL Provider: The certificate chain was issued by an authority that is not trusted.

    i found a certificate named with the SQL instance name in the Trusted People folder in sccm server
