Transport in BW

I had finished from extracting data to 2 infocubes in BW

One of them using data flow 7.0 and the other using 3.5 flow

This all done in DEV environment

So I need to transfer all infoobjects and InfoCubes and dataSources from DEV to QA then to Production

I need help in the required procedured to do this

And after the objects is transfred to the other environment what is other steps should be done as source system will be different?
