Migrate structured content and verify its rendering

How these skills work together

Inventory the original content and define a small target model before writing an importer. Convert HTML or Markdown into meaningful Portable Text blocks with explicit mappings. Render the converted fixture through the chosen frontend and resolve unsupported blocks before attempting the full migration. Keep the extraction snapshot and rerun strategy separate from the final cutover.

Validation and boundaries

Check counts, references, locales, rich-text semantics and live rendering. Include custom blocks, nested lists and inaccessible assets in the fixture. Rehearse redirects and rollback on a separate target; these skills have complementary roles but their interoperability has not been runtime tested by this catalog.
