Transfer questions

Hello everyone! I’m kind of new to this whole website and transferring so I apologize for any questions I have that may seem a bit redundant.
Okay so recently I’ve been accepted into UCI as a transfer student and I have some questions about attending the school. Once I submit my SIR for UCI, do I have to check out of the current community college I’m attending to attend UCI? Or can I just not enroll in my community college the following semester and just attend UCI, if that makes sense? I tried scheduling an appointment to talk to a counselor at my community college but the appointments usually do not fit with my schedule so I decided to ask on this website. I also looked around my current school’s website to see if there was anything about checking out of the school but I did not see anything, so I assume I just do not have to enroll in my community college again and can attend UCI. Sorry again, it’s my first time transferring so I’m a bit confused. Thank you to anyone who helps!
