What is the difference between insurance policy renewal and insurance policy remarket?

Insurance policy is a contract in utmost good faith between a customer and a service provider wherein the customer is obliged to pay an agreed premium in lieu of which the service provider e.g. the Insurance Company will cover life and/or movable/immovable properties against unforeseen eventualities. Whereas insurance policy remarket is a different scenario. In this case, the Insurance Company wish to remarket a policy withdrawn in the past, in new form and outlook with new features/incentives embedded therein.
