Change the underlying data type for the attribute, migrating any existing data where possible

Summary:Change the underlying data type for the attribute, migrating any existing data where possible.
This operation will attempt to generate new typed data values from the current value. Note this may result in an empty value
if no conversion can be made - however the original values will be kept allowing the process to be reversed, so this is not permanently lossy.

E.g. converting Text value '15' to a Real or Integer will produce expected results, but an original value of 'FIVE' would fail to parse.


Equally, some conversions make little sense, such as Logical converting to Date, and will be rejected..
Return Type: ODataResponseOfBoolean
