Unlike 1 - 2.5 Rooms and still different than 3 - 4.5 Rooms, moving a 5 or more room apartment is a big operation. You will need to plan with many days of packing and sorting and getting rid of stuff you won't take with you. After you are done, you will need a very big truck and a team of many movers to help you carry all your furniture, boxes and other devices. Besides, if you live on a high floor with no elevator and you have heavy furniture, you might also consider renting a crane.
