"Lost all my pokemon since soul silver... is there any hope?"

So yesterday I tried to transfer all my data to a new switch. Now, I was sooo focused on not loosing my island on animal crossing that I guess I followed the instructions wrong .. I logged into my nintendo account on the new switch and then I noticed it was gone on the old one... once I tried to log on the old one again it didn't matter, all my data was gone. Anyone know if there's anything else I can do ? Is there any hope for me to get years of pokemon and shiny back? I was so attached to some of these pokemon :(..(The only good thing that came out of this is that I did not loose my 400+ hour island in animal crossing lol..) via /r/pokemon https://ift.tt/3reWdkg
