Sites is fully integrated with Drive and other Google Apps, letting you add files, images, calendars, maps and other resources with ease. And just like Google Docs, you can share sites with teammates to collaborate in real-time.
The classic version of sites will remain active for at least one year and Google has stated there will be migration options to help move "old" sites to the new service in the near future.
Here's what’s special about the new Sites: Just like Google Docs, the new Sites is really easy to use and allows you to collaborate in real-time. Sites look great on any device by default. Deep integration with Google Drive makes editing, managing, and sharing sites even easier.

And any sites created on the new product will continue to work once it launches to everyone.
