We are running WAS 640 + portal + KM on our production server (UNISYS consolidation server on which most of critical applications of our customer are running).
For high availability reasons we immediately have to migrate/move/copy the entire installation of our server to another environment which contains two strong servers in cluster (MSCS). The new environment is also will be in 640 version. Notice that the name and IP of the new machines will be deferent from the original one. The majority part of our contents is on KM.
I would like to get advice about the following issues:
1. Which components need to be failover mode? In which mode (Active-Active or Active-Passive)?
2. What is the faster and simple way (But official and right way) to perform this mission in minimum risk? Should I perform copy installation process?
3. Is it possible to keep the original DB (assume that the consolidation server has the solution of high availability for databases) on the old machine and point the new servers to it?
Thanks in advance
