+# Qdrant Edge Migration
+
+- Status: Active
+- Introduced: 2026-06-02
+- Remove after: 2026-12-02
+- Code references:
+  - `runtime/src/qdrant_edge_database.rs`
+
+## User Impact
+
+Older installations may still contain Qdrant server sidecar binaries or directories after upgrading to a release that uses Qdrant Edge.
+
+Without this shim, obsolete Qdrant server files could remain in application data or bundled resource locations even though AI Studio no longer starts or uses the separate Qdrant server process.
+
+## Compatibility Behavior
+
+When Qdrant Edge starts, AI Studio checks known previous Qdrant server sidecar locations and attempts to remove obsolete `qdrant` and `qdrant_test` files or directories.
+
+On Windows and macOS production installations, AI Studio also checks the executable directory for old `qdrant.exe` or `qdrant` sidecar binaries. Missing paths are ignored, and failed cleanup attempts are logged without blocking Qdrant Edge startup.
+
+## Removal Checklist
+
+- Remove `remove_obsolete_qdrant_sidecar_files`.
+- Remove `remove_obsolete_qdrant_path` if it has no other callers.
+- Remove the startup cleanup call from `start_qdrant_edge_database`.
+- Update this document's status to `Removed`.
