It is best practice to remove all the contents of your wardrobes, cupboards, shelving and cabinets. You should pack the contents away into strong boxes, plastic storage bins or vacuum packed sleeves. Also do your best to remove any food crumbs to avoid attracting vermin.
As for the rest of your larger house hold items if possible, it's good to remove the legs and feet of items to increase the amount of storage space and reduce possible damage. This especially applies to bed bases and tables.
