Can you move the 1.2 progress to 1.3 if I release the 1.3 version with the 1.2 version clear? So what about it? I want you to me in detail

Yes, you'll be able to transfer your save file.  Just copy and paste all of the files found in the save folder from Beta 1.2 into the new save folder in Beta 1.3 when it's released! =)
