Old Ebonheart still exists in modern day, as far as we know. New Ebonheart was most likely destroyed when the asteroid above Vivec fell and destroyed that city as well.

Vivec is also most likely dead, thought officially he is just missing. But he did lose his immortality and his god-like powers so any number of things could have killed him in the 200 years since he was last seen.
