Guys, I swear I literally purchased a 2nd unraid license to run on a 2nd server for tinkering so I don't mess up my main server. But somehow I end up doing this on my main one anyway. I just never learn. I ended up solving the issue myself. I went into ZFS master and enabled destructive mode. Then changed the name of the dataset and the dataset location to appdatatest and then all my old appdata popped up exactly where it was before. Everything works fine now.
