"Pages" tab on 7.0 disappears while migrating content to 7.1

I had on old website template I was using on 7.0 and after experimenting with a template on 7.1, I decided to migrate all my old content from 7.0 to 7.1. I cancelled my subscription on 7.0, upgraded my 7.1 trial site and resubscribed. I then moved my domain from the old template to the new template. However, when I try to access my content from the 7.0 site, it seems to have disappeared. I had a "home", "projects" and "about" section in the navigation and it seems that the projects section has completely disappeared. I don't want to have to re-write project descriptions if I don't have to, but is there any way that I can access them again? The "Pages" tab isn't even showing up in the old 7.0 site.
