H1B Status is revoked, Visa NOT stampped, is transfer possible under cap-exempt?

Hi Experts,Please help me.1. I had a H1B approved petition which has expired in dec 2015. The petition was approved on 2013. The visa is NOT stamped.2. Petition was filed by employer X in india, now I am employed with employer Y in india.3. I have never travelled to US before.4. I have the soft copy of I797 with me and I am willing to travel to US ASAP.5. I just find that the status for my H1B says its Revoked.Questions?1. What does status “Revoked” mean?2. Can it be renewed? Can employer Z transfer the petition with them? and get the visa stamped under cap exempt?Thanks,Som.
