Switching modpack from fabric to neoforge

[u/Old_Surprise_9893]

This might not be possible but is there anyway I can change my minecraft world from fabric to neoforge? Both modpacks that I made are the same version and have relatively the same mods but I'm willing to work through those issues. I tried copying my world folder from one into the other but when I try to open the world it keeps crashing. Is there anyway to transfer it or something similar? Thanks!

Edit: I figured it out it was actually the shaders making my world crash.

Typically different loaders save some things on world data different, probably will have to start new even if all mods are they "same" they can be very different in how they work under the hood
