I am tasked with upgrading our current Business Objects environment from 3.1 to 4.0. I recently attended the BOE320 training course and found it informative for version 4. However, we did not cover upgrade methodology and scenario. I've read about the Upgrade Management Tool and have found this to be very helpful http://wiki.sdn.sap.com/wiki/display/BOBJ/How+to+Upgrade+to+BI4.0
My question(s) are more from a design aspect. The documentation recommends using a hardware load balancer between the cluster of SAP services. We have a vmware environment, and would like to use Microsoft Network Load Balancing clusters instead of a hardware appliance. If we choose this route, what other considerations would I need to make for my CMC cluster servers? Are there any caveats with using this method?
