Furthermore, it would be preferred if the move could be performed during a time that is not business hours in the US, although it does not need to be the middle of the night. Starting at 1600-1700 Pacific time would be acceptable. The Zimbra installation is "Stock" (no custom modules), and there is a working backup system. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
