## Upgrading from the previous app

Users of the earlier prototype should use the upgrade workflow instead of manually copying files into the new layout.

Recommended upgrade path:

Keep a separate backup of the old knowledge-base folder.
Start the new app.
Open Knowledge Base → Setup / Migration → Import / Upgrade Legacy KB.
Select the old knowledge-base folder as the source.
Select a new destination folder for the upgraded v2 workspace.
Let the app copy the useful data.
Run Check KB Compatibility.
Run Rebuild All Encodings if the report recommends it.
Review the generated upgrade and compatibility reports.

The upgrade workflow should copy data into a new v2 workspace. It should not modify the old knowledge base in place.

Old encoding banks may lack newer metadata, especially body-recognition pipeline metadata. If the compatibility report mentions missing or incompatible metadata, rebuild all encodings.
