My kid is asking to downgrade the Minecraft server to 1.8.9 for some reason. I tried to replace the minecraft_server.jar file in the installed docker by a new one which is supposed to have the 1.8.9 server (https://mcversions.net/download/1.8.9) but it still loads the server as 1.17.1. 1. Is a downgrade possible with this docker image? 2. If so, how do I do that? Thank you
