All files disappear!

I just get new VPS then do as DH recommended by moving two of my websites via “Manage Domains” to new VPS. After that I checked my websites and I lost all files in there. Sent 2 tickets with no answer!! This is horrible!! Any advise would be really appreciated. Thank you very much!
For more info, I have downgrade my VPS and decided to upgrade again. After checking around, look like all my files are in “deadpool”. Working to get it back. Hope I will be luck.
