Sure, perfectly possible, although this has nothing to do with QlikView. Just define an alias for your server in your DNS database (on the domain controller or wherever the DNS service is running), e.g. http: // qlikview /... alongside the regular http: // serv01qvw/... or whatever the old server is currently called.
Once you get the green light, change the alias to point to the other - new - server. Users can reach the AccessPoint via an URL like http: // qlikview / qlikview (drop the spaces) without really knowing what machine they'll be accessing.
Your System Administrators know what to do.
