The issue we are trying to overcome is how to build the new servers with the same names and IPs while still running...
our existing servers.
The best solution is to use virtual host names. The virtual hostname is an alias in DNS linked to a physical server. Every SAP GUI, interface and even possible, SAP itself connects to this virtual host. If the hostname changes, only the DNS alias needs to change to switch from one system to the next, to make the system accessible.
