Legacy Repository Activity Scanner for Migration Teams

## The problemWhen a company is mid-migration into a modern BI platform, the hardest question is 'where are people still working around it?' Legacy spreadsheets and files live across multiple cloud storage tools, leadership is guessing what to migrate next, and there is no scoreboard for whether the transition is actually working.## What this app doesA migration prioritization workspace. Connect cloud storage repositories and the app surfaces which legacy files have been edited recently, by whom, and how often. A treemap shows folder-level hotspots; a Ready-for-Migration list flags files with high recent activity that have no analytics counterpart yet. As things move into BI, the active-legacy count visibly drops — proving the program is working.## Key takeaways- Active-legacy file count as a single migration scoreboard- Hotspot treemap pinpoints folders with the most edits- Migration candidate flagging gives a weekly to-do list- Dormancy detection clears archive candidates from the noise## Who it's forBI directors, technical leads, and CTOs running a multi-quarter migration off legacy file storage who need a credible signal of where workarounds still live and whether the program is closing them.
