 Die Anleitung ist bewusst als wiederverwendbare Checkliste fuer weitere Legacy-Pakete formuliert. Sie trennt zwischen belastbaren Ergebnissen, verworfenen Zwischenansaetzen und Punkten, die bei jeder Extension erneut geprueft werden muessen.

+### Deinstallation
+
+Eine Sandboxed Extension unterstuetzt die Matrix42-Paketdeinstallation nur, wenn das Paket eigene Uninstall-Skripte mitliefert. Fuer dieses Paket gilt:
+
+- `uninstall.xml` entfernt den WebAPI-Service, alle eigenen Webservice-Operationen, Actions, Data Queries, die F4SD-Navigation, den F4SD-Quick-Call, die F4SD-Rolle und die eigene Lokalisierung.
+- Die vier globalen C4IT-Navigationseintraege werden nicht entfernt, weil sie von weiteren C4IT-Paketen gemeinsam verwendet werden koennen.
+- Schema, Pickup-Werte, Konfigurationseintrag, Dataset-Views und Previews bleiben als Konfigurationsdaten bestehen. Deshalb ist `uninstall_data.xml` absichtlich leer.
+- Der abschliessende Post-Schritt entfernt die `dat`-Eintraege dieses Pakets aus `SchemaScripts`, damit eine spaetere Neuinstallation die Installationsskripte erneut ausfuehren kann.
+- Jede `.del`-Datei verwendet nur eine aus dem Installationsobjekt oder einem Matrix42-Herstellerpaket verifizierte Kombination aus `ObjectId` und `TypeId`. Typ-IDs duerfen nicht geraten werden.
+
+Beim Hinzufuegen eines paket-eigenen Objekts muss immer geprueft werden, ob auch `uninstall.xml`, eine passende `.del`-Datei und `UnregisterInstallScripts_Sobu.post` erweitert werden muessen.
