Hi sai,
As you said your development in quality then I do not think you need to worry because BASIS will move your transport from QA to production..One important point you can not change anything in quality.
While collecting the objects in development I would suggest keep transport object wise means
dso's in one transport, cubes in another ects so it is simple to solve any issue comes.
Please validate all objects are active and correct in Qa before move to production once.
