How do I determine if a sql update is required for upgrade?

Hi There,

I’m taking over a site from someone, and wanting some confirmation before I do an upgrade.

Currently at 2.2.1

Download 2.3.0 and unpacked the files

I don’t see an upgrade.sql or anything, but wondering how I determine if sql updates are required as part of this install?

The information I’ve found is to literally just upload and overwrite the existing files on the server with the ones in the upgrade.

Looking for confirmation on this as I haven’t found a “these are the checklist to update and here’s things to look for” type info.

Thanks.
