Client copy from pre-production to production

Dear Experts,

We are implementing SAP to one of our clients and go-live is very near. As we don't have enough time upload master data etc., into Production server and check everything again, we would like to copy SAP_ALL from Pre-Prodcution client to Production client. we have QAS & Pre-PRD clients are on same server .Can we do it and Is this the best practice?? is there any non-compliance in doing so??

I found one link . but still looking for some inputs/ suggestions. Please help.

Thank you in advance,
