SPDD and SPAU transports

Hi Experts ,

I am upgrading  ECC 6 EHP6 stack 5 to Stack 12 ,  SPDD and SPAU objects are not same as DEV, QA and Production , we have more objects in DEV compared to QA and production as some of the modifications are still in DEV. Now project team wants to move the all modifications with SPAU and SPDD to QA and PRD.

We want to add all SPDD and SPAU objects ( from DEV) with the transports (  one transport for SPDD and one for SPAU )  when SUM prompts for QA and Production ,  Just wondering if it is going to be a problem while adding these transports with QA and Production upgrades.

Thanks
