 | 8 | +[WARNING]  | 
 | 9 | +====  | 
 | 10 | +Due to the new clustering architecture in Neo4j 5.x, the behavior of the `unbind` command has changed significantly compared to Neo4j 4.4.  | 
 | 11 | +
  | 
 | 12 | +Running the `unbind` command on any number of servers may result in the loss of cluster quorum, severely affecting clustering functionality.  | 
 | 13 | +Therefore, it is strongly recommended to consult with Neo4j Support before using the `unbind` command.  | 
 | 14 | +
  | 
 | 15 | +In Neo4j 5.x, use the `unbind` command only when troubleshooting **a specific server** and remember there is no guarantee that the allocator will reassign the same databases to this server, potentially resulting in orphaned database stores.  | 
 | 16 | +
  | 
 | 17 | +The `unbind` command preserves all database stores on the server; and when the unbound server is restarted and enabled, it is seen as an entirely new server.  |
