+## PostgreSQL Migration
+
+To move from SQLite to PostgreSQL, start the app with a PostgreSQL database URL
+and point `AMNEZIA_FELLOW_MIGRATE_SQLITE` at the existing SQLite file:
+
+```bash
+AMNEZIA_FELLOW_DATABASE_URL=postgresql://user:pass@postgres:5432/amnezia_fellow
+AMNEZIA_FELLOW_MIGRATE_SQLITE=/data/amnezia-fellow.sqlite3
+```
+
+On startup, the app runs its migrations on PostgreSQL, opens the SQLite source
+read/write, applies any missing app migrations there, copies config entries,
+database sessions, users, OIDC links, Telegram link state, and VPN clients,
+then writes an import marker into PostgreSQL. If the marker already exists, the
+import is skipped. If PostgreSQL already contains app data but has no marker,
+startup fails instead of merging two databases implicitly.
