It is never advisable to file a COS from B1 to H1B. If you do that, then you might be questioned when you attend the visa interview the next time. The best option is to file the H1B as a consular process (instead of COS) and when it gets approved, leave the country, get the H1B stamped and return back in H1B visa and start working for the H1B sponsor.
