I have a 1.14.4 server with the Vanilla server jar file. If I swap it for the 1.15 jar file, will there be any problems? I know the world will update okay, but will any configuration files get messed up?

It should just work, yes (of course you also need to restart the server). That's like updating your regular Minecraft game and opening an existing Singleplayer world in the new version. But it's always a good idea to make a backup before doing the update and keeping that around in case anyone finds problems later.
I play on a medium sized server that was updated to 1.15 the day after the release. The only issue that caused even this one day wait time was that a mod needed to be udpated.
