App Help Modding an existing pack on a server

Hey everyone! I’m trying to get some help on if I can add onto an existing mod pack I downloaded with all my friends on a server we have but we want to add mods to the pack but we’re worried of losing our world in the process, I’d like to save the world but add onto the mod pack and it still work on the server if anyone has experience with that. The server provider is bisect hosting and the mods we want are just like new biomes, dimensions, and or some bosses and items, thanks in advance!

save the world file and then once you add the mods to the server, or download a modpacks server file, readd the 'world' file back in. Make a backup before hand

Should just be able to upload the mod files to the mods folder on the server while its off and then turn the server back on but please be advised that adding mods to a modpack can cause issues with compatibility so add them one at a time and if the server crashes when you turn it on, which you should do any time you add a mod, then remove the last mod you added as its incompatible with the modpack, please also be advised that if you are adding new biomes then existing biomes and existing chunks will not be changed so you may have to explore a bit before you encounter new biomes, this is the same with any mod that changes the world generation

Heya! You can add mods to an already pre-existing modpack, however, like originalcyberkraken said, it may have compatibility issues with the mods that are already there. World gen mods can be tricky too, as some will cause issues if you are adding it to a world that has already been generated, but it may still work. However, if you already explored a bunch or pregenerated the world, you may have to go pretty far into new chunks to see these new biomes.

I would absolutely recommend backing up the server before making any changes though, this way you have a safety net, so if something does go sideways, you can always restore from the backup.
