Final answer:
A modular architecture is best suited for supporting integration based on code migration.
Step-by-step explanation:
The best architecture for supporting integration based on code migration is a modular architecture.
In a modular architecture, different components or modules of a system can be developed and tested independently. This allows for easier integration and migration of code when changes or updates are needed.
For example, if a software system is built using a modular architecture, developers can work on different modules separately and later integrate them seamlessly by migrating the code. This approach offers flexibility, scalability, and easier maintenance of the system in the long run.
