Excluding the fact that you want to do a client copy... the 
first thing you need to sort out is that both are the same 
patch level...

Now... as far as i can see you want to do a client copy 
from QA to Prod... I'm wondering why???? if this is a new 
production system the best will be either to do a 
Homogeneous system copy which will level your patch levels 
(as i presume production is behind) or to do a DB restore 
in production...]

Now if the system is not a new system... then why a remote 
client copy from QA? are you creating a new production 
client??? if thats the case, again you need to level the SP 
to avoid potential issues.
