 You can use the `neo4j-admin server unbind` command to remove and archive the cluster state of a cluster server so that it can rebind to a cluster.
 
+[WARNING]
+====
+Due to the new clustering architecture in Neo4j 5.x, the behavior of the `unbind` command has changed significantly compared to Neo4j 4.4.
+
+Running the `unbind` command on any number of servers may result in the loss of cluster quorum, severely affecting clustering functionality.
+Therefore, it is strongly recommended to consult with Neo4j Support before using the `unbind` command.
+
+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.
+
+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.

 To remove the cluster state of a server, run the `neo4j-admin server unbind` command from the _<NEO4J_HOME>_ folder of that server.
 When restarted, an unbound server rejoins the cluster as a new server and has to be enabled using the `ENABLE SERVER` command.

 === Turn a cluster member into a standalone server
 
 To start the Neo4j server in single (standalone) mode after unbinding it from the cluster, verify that xref:configuration/configuration-settings.adoc#config_initial.server.mode_constraint[`initial.server.mode_constraint`] is set to `NONE` in xref:configuration/neo4j-conf.adoc[The neo4j.conf file].
