Change Employer After H1b Approval Under Premium Processing

[rockymountain]

Hi,

Let's assume, I am currently working for employer A on OPT ending in Aug end. And employer A has filled my H1B under premium processing.

Now, I would like to know can I change employer after getting H1B approval and before OPT ending and actual H1B comes into effect(Oct 1) ?

Thanks in advance for your feedback.
