One thing to note:
If you're using Sup2/Sup3, you're not going to be seeing flows that are 
punted to the MSFC in the version 7 exports.  With Sup2/Sup3 this is 
likely to be very few flows (hopefully), but with a Sup1 or 1A you'll 
miss a bunch of flowdata, so be careful there.

You used to have to collect both version 1,5,6 flows from the MSFC, and 
version 7 flows from the SP/PFC.  I think after around 
12.1(13something)E this changed so that the PFC sent stuff up to the 
MSFC for export in version 5 flows, combining things and making your 
life easier..

In any event, with newer software on either Sup1/2/3, you can set it to 
ver 5 and your collector should be able to deal. 

Note that v8 is aggregated flow information and as you indicate, it 
makes no sense in the context of a receiver expecting non aggregated 
data. Whereas v1, v5, v6, v7 are similar (ish) in that they are 
non-aggregated flow information.
