Can I install a second Trados Front end while the existing server is running.

Our team needs to rebuild the server currently hosting the Trados Front end.  Can I install the software on the new server and license it while the existing server is still running.  I want to verify the functionality before announcing the new server to our clients.   Can there be two front end servers running at the same time?
