Upgrading to MN4 app for ios

I’m a longtime-time MN3 iOS app user on my iPad and am considering upgrading to MN4.

  1. If I do so, will my existing MN3 files automatically open in MN4, or is there something I have to do to ensure those files copy over without issue.
  2. Also: does MN4 replace my MN3 app, or will I keep the MN3 app and get MN4 as separate apps?
  3. If I decide I want to revert to MN3 after upgrading to MN4, is that possible — with all my files fully intact?

Thanks.
