Things have changed over the years. It's now much better to book a group when the itinerary is first opened for booking - we get the best rates and the best amenities. Plus, they only hold aside a certain percentage of space for group booking. Sometimes, it does behoove an agent to establish a group and then move bookings into the group - depends on the pricing and the amenities. Some cruise lines allow it without canceling the existing reservations and others do not. Sometimes the going rate is cheaper than the group, so we book into individual reservations and then move them into the group, thereby getting the best of both worlds. Each cruise line is different on what we can do and how we can do it, so no one way fits every situation. And sometimes, even though there is a group, it's best for the agent to book the client into individual reservations and leave them there than to transfer them into the group.
