Even years later, a town wouldn't just move on over.
With certain exceptions. For instance, here in Alaska, present day Seward is actually a fair distance from where it was even in 1963. The whole town picked up stakes (pun not intended but welcome) and moved after a massive tsunami wiped out much of Old Seward in 1964.
So towns can move, but barring things like natural disasters, they don't tend to do so.
I'll leave it up to each of you to determine if Dracula-related things would count as a disaster worth moving a whole town over.
