For importing into face to face, the main tables of interest are:
| Table | Purpose |
| facetoface | One entry per facetoface activity |
| facetoface_sessions | One entry per session |
| facetoface_sessions_dates | One entry per session date (for sessions that span multiple dates) |
| facetoface_signups | One entry per user per session |
| facetoface_signups_status | Stores the current and past sign up statuses |
Courses are a bit more complicated, you might be better off creating an empty course and restoring it from a backup.
