Long-lived Tumblr blogs accumulate multiple domains, slug variants, archive pages, tag routes, and external media dependencies.
Reconcile by post type
Compare source, extracted, transformed, loaded, skipped, failed, public, draft, and queued totals.
Inspect representative eras
Review old and recent posts, every post type, NPF, photo sets, embeds, reblogs, notes, tags, and deleted-media cases.
Crawl URL families
Test custom-domain and tumblr.com paths, /post/ IDs, slugs, tag/archive routes, redirects, canonicals, and internal links.
Monitor after cutover
Check files, embeds, crawl errors, sitemap entries, analytics, high-value posts, and documented exceptions.
