{{< note >}}
This command's behavior varies in clustered Redis environments. See the [multi-key operations]({{< relref "/develop/using-commands/multi-key-operations" >}}) page for more information.
{{< /note >}}


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`]({{< relref "/commands/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.

## Examples

{{% redis-cli %}}
SET mykey "Hello"
RENAME mykey myotherkey
GET myotherkey
{{% /redis-cli %}}

## Behavior change history

*   `>= 3.2.0`: The command no longer returns an error when source and destination names are the same.
