my sql server db is. version 16, but my web host only runs version 15. what to do?

Question

I asked my provider for help to get my v.16 database running. They support up to v. 15. If they can't get my db running, is there a way to convert it down?

Or find another provider?

Answer 1

15 = SQL Server 2019, 16 = SQL Server 2022? https://sqlserverbuilds.blogspot.com/

is there a way to convert it down?

No, there is no supported way to downgrade a SQL Server database. You would have to script-out all objects & data.
