Migrated diagrams show old content
What you are seeing
Migrated draw.io diagrams are showing old content instead of the current drawing.
#Why it happens
When version history was replayed, the oldest version became the first version, and the migrated macro was left pointing at it. This has been fixed for new runs.
#What to do
Open Repair, choose Repair diagram versions, upload the run's log, scan, use the preview to check one page side by side, fix it, verify it live, then bulk fix the rest.
There is a tool for this: Repair diagram versions. It fixes the affected pages forward without re-running the migration.
