Installing new application

If I have a running server, what is the suggested way of updating an
application on the server?
Here is my current technique (below). I run one instance at once and this
technique works consistently for me, but requires me to shut down the web
server.

It seems like if I skip any of the steps, webobjects keeps using some cached
version of the old application. The sequence of steps (below) works, but it
is tedious and has more downtime than I'd prefer.

Is there an easier way to do this?
