hi my server has existed since 2019 on 1.12.2 and I'd like to update it to 1.16 at the least. I created another server to attempt updating it without messing with the original server and I've been using backups and updating versions using the same software (spigot/bukkit). As you can read from the title... its not working.
I actually tried this sometime in December as well. After it crashed I tried a method of just copying the worlds to the new server and one loaded perfectly fine but another loaded as an ordinary world with nothing in it... I don't know if it's relevant, but I thought I would add that.
I'm wondering if there's a way to fix my server or is it stuck in 1.12 forever? Could someone please help me through fixing it?
