+| *Syntax* 3+m| dbms.unquarantineDatabase(server, databaseName, operation) :: ()
+| *Description* 3+a| Remove the quarantine status from a database in a server performing a cleanup `operation`.
+The possible values for the cleanup operation are:
+
+* `keepStateKeepStore` -- do nothing, leave store and cluster state as it is,
+* `replaceStateKeepStore` -- join as a new member clearing the current cluster state but keeping the store
+* `replaceStateReplaceStore` -- join as a new member clearing both the current cluster state and the store
+.4+| *Input arguments* | *Name* | *Type* | *Description*
+| `server` | `STRING` | The name or the id of the server where there is the quarantined database.
+| `databaseName` | `STRING` | The name of the database whose quarantine status must be removed.
+| `operation` | `STRING` | Select a cleanup operation to perform while removing the quarantine.
+| *Mode* 3+| DBMS
+|===
+
+[NOTE]
+====
+If you choose to clear the current cluster state, the server will try to join as a new member,
+but this joining can succeed if and only if there is a majority of old members "letting" the
+new members in. Let's assume our cluster has a topology with three primaries. If there is only one server
+in `QUARANTINED` mode, then it is safe to choose `replaceStateKeepStore` or `replaceStateReplaceStore`.
+If there are two servers in `QUARANTINED` mode, then you should not use concurrently `replaceStateKeepStore` or
+`replaceStateReplaceStore` for both servers because there would be no majority to let them in.
