¶ Minecraft: How to Change Forge Versions
If you have a modpack that requires a specific version of Forge, or you want to play an older version for any reason, you can use these steps to launch your server in the proper version.
¶ Steps:
1. Download the Forge installer for the version of Forge you want to install from the official Forge website.
2. Open the File Manager
3. Navigate to /minecraft/
4. Upload your forge installer to this location
5. Go back one folder to / and right click docker-compose.yml then click Edit
6. Add a new line under TYPE: FORGE that says FORGE_INSTALLER: followed by the name of your forge installer file name. This will change both the Minecraft version and forge version. Save the file when you're done.
Note: If you are using a version older than 1.18, you must also change the image tag from latest to java8-multiarch
7. Save Config & Restart the Basic Server Settings
