[ ] Are sources, ownership and sharing documented? [ ] Is a backup available and access appropriately restricted? [ ] Have the trial, recurrence and time zones been checked? [ ] Has repeated import and possible duplication been tested? [ ] Have changes since the export been reconciled? [ ] Are the authoritative calendar, cutover and recovery path agreed?
