Sometimes, often after many years, the parties desire to continue an existing relationship but with certain amendments of the existing contract (e.g. in order to adapt the contract to newer standards of compliance, to align the contract better to the actual practice of doing business or to take out established ambiguities). In such case, the entire contract may be replaced by a restated and amended contract. (Online book: Drafting contracts)
