KW 70. Hardware Prerequisites and components ?

Hello,

We plan to adapt our existing KW 6.0 to the NW04 KW.

Does anybody know what could be the Hardware prerequisites ?

Currently we are working on two servers, one for the content and one for the SAP instance.

I saw on SAPNet that we need a IKS server, a PAW server and a HTML server.

But I did not see anything about the Content server. Does it means we use the Portal KM to store the content ? What about the TREX, is it the one of the Portal ?

Thank your for your help.

Marc.
