+Renames `key` to `newkey`. It returns an error when `key` does not exist. If
+`newkey` already exists it is overwritten, when this happens `RENAME` executes
+an implicit `DEL` operation, so if the deleted key contains a very big value it
+may cause high latency even if `RENAME` itself is usually a constant-time
+operation.
+
+In Cluster mode, both `key` and `newkey` must be in the same **hash slot**,
+meaning that in practice only keys that have the same hash tag can be reliably
+renamed in cluster.

+- `<= 3.2.0`: Before Redis 3.2.0, an error is returned if source and destination
