Moving SSL from Windows 2003 to Windows 2012

We are migrating all our websites from widnows 2003 to windows 2012 IIS.
It looks like simple export and import as I researched, but just to make sure.

I have Basic  SSL from Networksolution for a domain. I copied and configured the website in Windows 2012, it works. Now, I need to have SSL in the new server. Currently the domain DNS name and SSL are tied with Windows 2003. I'm trying to minimize the downtime of our website.

 Will this export and import shut down SSL on the old Windows 2003 server? Or the both SSL on both servers work together?

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing.

you can export the certificate at w3k3 server without interruption.
import this certificate, bind it within IIS manager and test the new server with IP or configure the name with the new IP at a test-workstations "hosts"-file. should work.
