Here's how you can upgrade to Minecraft 1.14:

UPDATE: Spigot (CraftBukkit) 1.14 has been released! Remember these are very early stages! Not all plugins expected to work.

***IMPORTANT NOTICE: The new release of Minecraft 1.14 is very unstable! It consumes more than double the RAM, and also locks out Minecraft's primary CPU cores causing your server to lag. We recommend that you stay on 1.13.2 if you can until Minecraft 1.14.1 is released. Or live with the lag!


1) Stop server, Go to PLUGINS AND MODPACKS section of your control panel
2) Look for Minecraft 1.14, and click INSTALL

OR for Plugin support:


3)
If you want to upgrade your existing world, click upgrade.
We recommend that you start fresh, so New install is best. (If you click new Install, your existing world and build will be stored in a safe place for you to play later)
