Not if you set your Zone Data Collector preference to Most Preferred, which it should be anyway. The latest version thing is used during an election when more than one server is set with the same preference level, or they are all left as default. The recommended order is for normal operational requirements. Putting a "test" server in a production farm is fine. Just ensure the Data Collectors are patched before deploying it to the rest of your production servers. Cheers, Jeremy.

Put your test VM into a test farm and test there.

I just built a test VM to do some testing, from the best practices web site I should install in the following order 1. Zone data collector 2. Backup zone data collectors 3. Database connection server (Resource Manager) 4. Primary farm metric server (Resource Manager) 5. Backup farm metric server (Resource Manager) 6. Member servers I don't want ot install on any of these servers first until I am finished testing. Will this cause me any issues?
