Hi @Sanjay Addagudi ,
Do you mean to upgrade SQL Server in-place? If I misunderstood, please feel free to let me know.
Please run the setup file you want to upgrade to as admin and start the SQL Server installation Center, then go to Installation on the left panel -> click Upgrade from a previous version of SQL Server on the right panel to start upgrade wizard. Please refer to this doc for more details.
If you want to upgrade an existing instance of SQL Server to a different edition, please go to the SQL Server Installation Center click Maintenance -> select Edition Upgrade.
In addition, please check this doc to ensure the edition and version of SQL Server is supported for upgrade.
Best Regards,
Amelia
