Completed internal migration ยท Did the export, migration and analysis

Team knowledge base migration: OneNote to Markdown to Confluence

Status: Export complete and shared with the team; Confluence import approximately 95% successful; limitations documented.

Problem
A team's knowledge lived in a OneNote environment that was hard to search, move or preserve with its attachments and history.
My part
I exported the full environment to Markdown with attachments intact, shared the export and approach, ran the Confluence import from a copy, and wrote up the limitations.
Exists now
A complete Markdown export, a Confluence space built from it, and an experimental map of which notes supersede others.
Results
About 95% of the import succeeded (my estimate; the denominator is not published). The supersession map is non-deterministic and is used only to help people review search results.
Limits
Internal work: no public artifact. The import rate is self-reported.

Evidence Internal work. No public artifact.
