Non-Compete applies to the new company?

I'm an employee of a consultanting company. I've assigned and worked for the same client as a contractor for more than a year. Now, my employer is being acquired by a competitor. I do not like the compensations and benefits of the new company. I do not know if I signed any non-compete agreement of my original employer. If I did, is the non-compete agreement still apply to the
new company?

Another company has offered me a better salary and benefits to work for the same client. The client has no problem as long as my work is not affected. I know that NYS disfavors the non-compete agreement which includes not to interfer with one's ablility to earn a
livelihood.

What I can do? with or without the assumption that I signed the non-compete agreement.

Thanks in advance.
