This is where Schema App can save you a lot of time. Go into Schema App and open one of your data items (ie. Contact Point). Then, click on Actions>change URI. Enter the new URL With https. Then, you will want to edit the data item and change the URL to have https. By just changing the URL, you will not have to re-enter all the other data and the markup will just get deployed to the new URL. We have a tutorial for this here.
