A completed scan gives you a summary and a detailed breakdown.
At the top, you'll see totals:

A visual bar showing what percentage of files are clean vs. which ones have each issue type. Green is always "ready to migrate." Other colors map to issue types.

If the bar is mostly green, you're in good shape. If it's not, scroll down to see which issue types dominate.
Each issue type gets a row with a count and a colored bar showing its share of total issues.

Click any row to see the full list of affected files in a modal. The modal is virtualized — it handles hundreds of thousands of issues without slowing down.
Each issue row in the modal shows:

Click Export CSV at the top of the scan results (or inside any issue modal) to download the complete issue list. Useful for sending to a client's IT team for cleanup.
If the scan finds files with blocking issues (blocked extensions, oversized files), those files won't migrate even if you hit Start Migration. They're tracked in the scan results and skipped silently during migration.
Non-blocking issues (path length, invalid characters) do attempt to migrate — SharePoint will either accept them or reject them, and the rejection becomes a migration error.
See Issue Types for what each issue means and how to address it.
