-- | Updates an alias to associate it with a different 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).
--
-- An alias is not a property of a key. Therefore, an alias can be associated
-- with and disassociated from an existing key without changing the properties
-- of the key.
--
-- Note that you cannot create or update an alias that represents a key in
-- another account.
