1) EINs are non-transferable so you will need a new one.

The above answer is not "legal advice" as specified under any pertinent rules governing the Professional Responsibilities of Lawyers and should not be relied upon. An attorney-client relationship has not been established by virtue of this correspondence. Legal issues are often complex and involve local laws and facts which may not be effectively communicated without a complete consultation.
I may suggest that you request, via email, the FREE MEMORANDUM on the advantages and disadvantages of legal entities...and also perhaps the memorandum of corporate compliance and properly maintaining your corporation.
