Even if you could, you don't want to. What you want to do is:
- Have at least 2 machines running behind a load balancer
- Take one of them out of the LB pool
- Shutdown the processes on it
- Replace them (binaries, resources, config, whatever)
- Bring them back up
- Then put it back in the pool.
- Do the same for the other machine.
Make sure your chances are backward compatible, as there will be a short period of time when both versions run concurrently.
