I am monitoring a site with lots of traffic, and there are a couple of people using the info for analysis on a daily basis. I want to try all sorts of stuff (progressive filters, etc), but i can't afford loosing information, even for one day. so i want to count traffic on the same site with a separate profile (on the same account), so i can use it for testing, while the original profile counts as usual. How can this be done? I'm currently using the old tracking code(urchin), do i need to use the new one (GA)? Do i need to put the code twice? two different codes? just the one?
