Is it possible to clone a production windows server (VMware VM) so you can test doing a application upgrade?

I have a production Windows server 2008 R2 running an application.  I need to upgrade the application and have users test the new version of the application.  I would like to do this without affecting production.

Is it possible to do this without creating a test server from scratch and installing the application and then upgrading the application?

The application needs to access an Oracle Database on another server.  

The testing of the application will involve a Windows 7 PC running a fat client program and connected to a scanner to scan documents.

Yes, if you have vCenter Server, just right click the VM, and select CLONE.

and then create an isolated network, for you to work in.

You can clone the existing VM to one other new VM and do the relevant new development on new VM.

In general yes, HOWEVER, make sure that "cloned" server NEVER, EVER sees the production network.  You may have to clone several systems to adequately reproduce the network to perform your test.
