I have a minecraft server with 1.15 version but now there's already 1.15.1 I want to change the version what I have to change / delete in order to upload / use the new version 1.15.1
As far as I know, just download the 1.15.1 jar file and then start it
Download new Minecraft server.jar with the current version and replace or spigot or paper whatever you have for a Minecraft server.
And what do I do with the 1.15 jar file and just delete the 1.15.1?
Well you have to first look at the server as the current jar is called. If the e.g. Server.jar means you have to rename 1.15.jar to server.jar and then replace it with the old one
It's called spigot-1.15.jar and what do you mean by replacing it now?
Then you also need the right Spigot.jar. It must be 1.15.1 …
Where do you host your server?
So simply upload 1.15.1 via minehub and delete 1.15?
If it's spigot, then yes…
You may have to adjust your start file, because the server is looking for the file name with 1.15 …
