## Contract Logic Migration

Contract Logic Migration is the process of moving from one version of a smart contract to another, usually to improve efficiency, add features, or patch security vulnerabilities. In the context of upgradeable contracts, this involves pointing a proxy contract to a new implementation contract.

This process must be carefully managed to ensure that user data and state, such as deposited assets or account balances, are correctly preserved during the transition. Migration often utilizes time-locked deployments to ensure that the transition is visible and can be challenged if it is deemed harmful.

It is a complex procedure that requires rigorous testing to avoid loss of funds.
