I am using two servers that host Windows 2008 with Hyper V. I would like to upgrade the setup to the current system, but please let me know if the upgrade can be acieved on live servers? Or should I purchase an additional server, test it and then replace it with the first one?

Upgrade current system on live servers

I am assuming that you have a single physical machine and have virtualized the same into two separate server systems. Although, I am not sure what you exactly meant by upgrade and if it is limited to software upgrade (Patch installation etc.), I do not see any issue as such except for the fact that you need to temporarily shut down any production system that might be supported by any of the servers by requesting an outage slot. Or may be perform it during non business hours.

However, if the amount of upgrade is not restricted to software or patch upgrade and involves much larger scope like increasing system RAM, disk space etc. then definitely this cannot be done in live environment and the system needs to be completed stopped for a much longer period and tested thoroughly post upgrade before it goes on live.
