I have a job that is interested in hiring me. The job requires .net programming experience, but they are willing to overlook that because I have so much Classic ASP expereince.

Here's the problem, im scarred of being hired for a job that I dont know 100%, but Im in no position to turn down a job that will allow me to relocate to the area Ive been wanting to move to forever.

My questions are:

What are the differences between the two?
Am I going to get in over my head?
Please describe as much as possible to help me out!
