German question

OK so when you guys take the kitchen with you when you move what do you if it doesn’t fit in the new apartment?

Too big - do you throw away the excess?

Too small - do you buy some filler or extra cabinets?

Or do guys just live with ill-fitting fixtures?

Oh yeah and as a follow up how do you even take the kitchen with you without destroying the countertop and or other parts
