Migrate your own DITA
Upload a .zip of DITA and get back MyST Markdown for Sphinx, with a report that names every difference from your published DITA. No sign-in is needed.
A .zip of up to 10 MB with your root map, its topics, key maps, DITAVAL files and images, in the folders they use. Topics must use the OASIS DITA DTDs; files that declare entities are refused.
Topics that pass every check are ready to merge. A topic that failed a check, or needs a writer, is still in the download; the report shows exactly what differs, so nothing is lost without you knowing.
