I have downloaded a trial version of SQL Server 2017. After installation I got this:

Microsoft SQL Server Enterprise Evaluation (64-bit)

I want to buy a license for Standard edition after some time. Can I use the same SQL Server instance and apply the new license to it without any downtime, upgrade/downgrade, or re-install?

You use the SQL Server installer to perform an Edition Upgrade. It doesn't actually re-install the instance; it just applies the product activation key for the new edition.

  • Relevant: learn.microsoft.com/en-us/sql/database-engine/install-windows/… You cannot upgrade from Eval to Express, and once upgraded cannot be downgraded to a lower edition (unless it's from Developer). But OP says it's from Eval to Std so that's OK.
