First, it is important to differentiate between a Group and a Department. A Group is created to facilitate Group Questions and contains group members. A Department allows you to set Department Objectives and no members exist in a department.
Your groups will not be synced with departments, so you will need to create new departments for objectives- even if you have groups set up for questions. You can read more about group functionality here.
