Well,
Do your research first. Sometimes not all credits transfers to University. It will be easy if you know which university you wanna transfer to. Sometimes, it won't be a problem if you transfer to the college/university of the same state. And keep in mind that the gpa you had in community college may not count in university and you have to start fresh. The classes in University are harder because, usually, they are higher level courses.
If you have any more question, feel free to ask.

Thanks
