Move a representative documentation section into Docusaurus with navigation, code blocks, images, and an older version if users need it. Have a contributor update a page through the normal review process, then check generated URLs, search, accessibility, and mobile layout.
Docs are a product surface. Keep build dependencies pinned and test broken links in CI. Before migration, plan redirects and the ownership of obsolete pages. Choose the system that helps readers find the correct version, not merely a pleasing theme.
