Need help for updating datapack

Can someone update a datapack for me? I don’t know anything about it, and I tried following some tutorials, but I don’t understand anything. I want to add this datapack to a server I have with my friends, but I don’t want to downgrade the server version. The original developer disappeared. 1.20.2 to 1.21.4 https://www.planetminecraft.com/data-pack/adrenaline-bosses-part-1-minos-prime/
