Additionally, the plugin supports both current and legacy theme structures, offering flexibility for projects with varying levels of legacy code. The SyliusUpgrade Plugin is essential for developers and e-commerce businesses looking to keep their Sylius applications at the forefront of technology with minimal disruption.
