Do you have any guideline and support link for update to version sp3.
The SQL Server Installation Wizard provides a single feature tree for an in-place upgrade of SQL Server components to the latest version of SQL Server.
Before upgrading, back up SQL Server databases and other objects associated with the previous SQL Server instance.
See this doc for more details: Upgrade SQL Server Using the Installation Wizard (Setup).
Regarding the support link, I would suggest you open a ticket to Microsoft support for help.
Best regards,
