He can certainly appeal and he is already working on it. But since I am not an expert on those kinds of things, and how the criminal law applies in the United States, it would be worth asking: does not he get the tag or get labeled as a convinced felon in the eyes of the American law system? or is it supposed to be waited after the appeal before he can get tagged as a felon.?
Because, to be honest, I believe there are many people within the country who identify themselves as Republicans and yet they have a high enough moral bar so they would not vote for a person who was found auikty of a felony in the State of New York (there are several other cases pending).
Being a felon could make Trump to lose the vote of the moderate Republicans, those who are not going to vote for a democrat in any situation, but still they could not find themselves to send a felon to the white house. I am expecting to see how this conviction and the appeal could change they odds on the betting markets in the end (assuming there will be even a reaction by the markets).
