RENAMENX key newkey

Renames key to newkey if newkey does not yet exist. It returns an error when key does not exist.

Note: Before Redis 3.2.0, an error is returned if source and destination names are the same.

Return value

Integer reply, specifically:

  • 1 if key was renamed to newkey.
  • 0 if newkey already exists.
