Upgrade angularjs 1.6.x project using the Component API and Lazy Loading to Angular(version 6)

I have read Angular’s official document for upgrading from AngularJS to Angular. But I unable to find some proper documentation for Lazy Loading of Modules. My project is in AngularJS 1.6.x and I have used Components and Lazy Loading features. Can anybody guide me how to proceed? Thanks in advance.
