How do I update the forge modloader when using the old manual Curseforge server type?

[hamcoremusic]

So after trying to get BMC4 to work through AUTO_CURSEFORGE and MODRINTH I decided to revert to the manual Curseforge option and it worked way better. The server pack just has a lot tied to it that the auto downloaders didn't work with.

Now v28 of BMC4 came out and it requires a bump in the Forge mod loader version. How would I go about this? Would I just change the pack name to the new version and let it run it's course?

My only issue with making the container unpack the server is it might overwrite my variables.txt and server properties. Can I safely remove those out of the pack and it still remains functional?

Or can I just change the Forge version to the one I need in variables.txt?

The old approach is deprecated for several reasons but mainly because every server modpack is a little different. You'll need to investigate that variables file and the modpack supplied script to see if that solves your scenario.

Looks like I just has to make sure I brought over the start.sh script and copy my custom flags to the variables.txt file. It reads the version it needs from the variable file so it auto-installed using their script
