Order ID migration

Order Number is parseInt/long and check/compare from the list of number range, to determine belongs to which mall.

In this migration, order number will be alphanumeric, that it will hit error or fail to be checked from this kind of checking, example:

            long iOrder = Long.parseLong(orderNum);
            if (iOrder >= 400000000 && iOrder <= 419999999)//HK Mall
                keepOriginalPurcQU = true;
            else if (iOrder >= 440000000 && iOrder <= 459999999)//Aus Mall & Ind Mall 
                keepOriginalPurcQU = true;

To make it consistent for future alphanumeric order number case, can consider remain this logic checking by using customize comparator for the string value. For reference: http://code.hammerpig.com/sort-strings-numbers-java.html. Or have better resolution, if any.
