+**Critical Considerations**
+
 **Before enabling multitenancy on an existing installation:**
 - Data loss risk: File vectors and user memory vectors are NOT migrated automatically. Only knowledge base content can be reindexed (migrated).
 - Collection naming dependency: Multitenancy relies on Open WebUI's internal collection naming conventions (user-memory-, file-, web-search-, hash patterns). **If Open WebUI changes these conventions in future updates, multitenancy routing may break, causing data corruption or incorrect data retrieval across isolated resources.**
