Another lesson of Ikea is that often you cannot move them from one home/apartment to another, because if you try to take it apart and then reassemble it, it's never the same. To extend this via analogy to the software realm, a deep refactoring is problematic whereas OTOH a complete rewrite is a better idea. Which has not borne borne out by industry experience.
Most stuff doesn't even need disassembly. My bed is Ikea and has been dissasembled and reassembled twice, no problems.
