-- Updates an alias to map it to a different key.
--
-- An alias is not a property of a key. Therefore, an alias can be mapped
-- to and unmapped from an existing key without changing the properties of
-- the key.
--
-- An alias name can contain only alphanumeric characters, forward slashes
-- (\/), underscores (_), and dashes (-). An alias must start with the word
-- \"alias\" followed by a forward slash (alias\/). An alias that begins
-- with \"aws\" after the forward slash (alias\/aws...) is reserved by
-- Amazon Web Services (AWS).
--
-- The alias and the key it is mapped to must be in the same AWS account
-- and the same region.
