Configs will all stay the same, we only refresh them sometimes. Only the Files will be totally reworked due to the completely different control mechanics we are using now. Maps, Mutators etc. will stay the same unless we found some cool new stuff.
Imagine three dedicated servers. Three copys of the server files. Now we dont copy those files, we only create links to the original files which are never changing (eg. ucc-bin, which basically is UT2004.exe for a server) and only create copy's of files which can change. (CustomMaps, Configs, etc.) In this example we can reduce our harddisk-usage about 66%. And the more servers we run the more disk-space is saved. (And compared to any other private organisation we host tons of servers for multiple games... and that on one single machine!)
Despe (that is Donzi and me o/) is running two Rootservers. One Server is running Virtual Servers (containing UTzone.de and Websites of Customers, also email and stuff) and the other one is running our gameservers which is quite more expensive due to the better internet connection (ping!). We rent these rootservers (read: real hardware) and use them to provide services for our customers and of course UTzone-Users.
Hope i could provide the information you were looking for.
