Transfer once..then transfer back? A re-admit or re-applicant?

So I just finished my second semester of college at a good LAC I transferred into from a very well ranked liberal arts school… I am having qualms about my move. I though this change would be more comfortable and less challenging, and only now am I starting to think that I am doing myself a discerning by going to the “easier” school. I miss the school, but the old school also has the degree that I am going for now that i’ve had some experience in college to decide. Also, this school has the graduate program I would also like to follow up with.

So if any one knows, is this situation me transferring back or me registering as a re-admit?

Thank you and I apologize for any confusion

Ask the dean at the school, the rules may be different. I I’m in the exact same situation like right now, and when I asked they told me that because I enrolled at a new college I have to transfer aka re-apply.
