H1B transfer after I-140 approval

[ariv_anand]

Hi All,

I currently work for employer A in H1B status. I am completing my 6th year on May 2012. My employer A applied for the H1B extension and i got my extension until May 2015

I also have an approved I-140 in EB3 category from employer A with the Priority Date: 2/10/2011.

I have a couple of questions regarding transferring my H1B to employer B

1. Is it safe to transfer my H1B to employer B and start my new job ?
   
2. If my employer A revokes my I-140, will it void my H1B that was transferred to employer B ?
   
3. If my employer B is willing to start a new GC processing in EB2 category, can I port my previous priority date ?
   

I would really appreciate a response to my questions since I am looking for a change quickly.

Thanks in advance
