+# Prowlarr on media-core
+
+- URL: `http://192.168.50.46:9696`
+- Appdata: `/opt/media-core/appdata/prowlarr`
+- Source: stopped `.10` Prowlarr appdata migrated on 2026-09-23
+- Source rollback archive: `.10:/root/migration-backups/prowlarr-20260923.tar.gz`
+- Source archive SHA-256: `bc6743ba212647c3af22d7c5caa759ea113c5d27d8f0e2bdf52748862110bbfb`
+
+The migrated database primarily supplies the enabled Torrent indexers
+`TheRARBG` and `IPTorrents`. NZBHydra2 remains the Usenet aggregator.
+
+The source app used Docker-internal application URLs and old 4K endpoints.
+After deployment, Prowlarr applications must target the unified media-core
+Sonarr and Radarr instances and advertise `http://192.168.50.46:9696` as the
+Prowlarr URL.
