What are the migration paths between them?

I can only answer questions about chrisbanes/android-pulltorefresh or yunaiv/yudao-cloud.

The two repositories you're asking about serve fundamentally different purposes and have no migration path between them:

• chrisbanes/android-pulltorefresh is a deprecated Android UI library (Java) for implementing pull-to-refresh gestures on scrollable views like ListView and GridView. It hasn't been maintained for 9 years, as noted in the README [README.md:L1-L4].

• yunaiv/yudao-cloud is a backend Java cloud platform with database schemas, Flowable workflow integration, and SQL migrations across multiple database systems (MySQL, PostgreSQL, etc.).

These are unrelated projects with different domains:

• One is legacy Android UI widget code
• The other is a modern enterprise backend system

There's no meaningful migration path between them. If you're working with an old Android app using pull-to-refresh, you'd modernize to contemporary Android patterns (like Jetpack's SwipeRefreshLayout). If you're deploying yudao-cloud, you'd set up its database schema independently.

Are you trying to integrate pull-to-refresh into an Android client for yudao-cloud, or asking something else about these projects?
