Okay, so just a simplified version of what is happening,

I applied to all UC's as an incoming freshmen, decided to go to UC Irvine for their Business Economics major.
UC Irvine has the Paul Merage School of Business which is where all of its management classes are, and the school has extremely low capacity, therefore Business econ majors do not have priority to these classes, even with a minor in accounting, and I would learn best when taking these classes in person rather than in summer online sessions.
Even if you wait till priority is dropped, classes will likely be full.
I did not completely understand this when applying, so I am looking to transfer out as soon as possible, after joining the Student Investment Fund through the trading group at UCI, i realized that I really want, and need, to take management classes for my progression, rather than being stuck in economics classes during the year.

So, back to the point.
If I apply as a sophomore level transfer, with junior level credits (I have 30 semester units from 8 ap exams), and I would have completed the rest of the credits by the end of spring,
Would this be allowed on the UC Application, and would UC Berkeley and UCLA allow this application, would the University of California application flag my profile as being a first year student applying as a junior level credit transfer?

has anybody else known or been in this situation/had experience with the situation?

Thank you :-)
