Right, I can understand that this wonderfull tool does not support "implace upgrades" and I can both understand and accept that, however I need to UPGRADE

As I need to bulk upgrade a number of machines it would be REALLY nice to have a way of deploying this.
Does anyone know of a commandline tool to achive this? I tried to download the upgrade tool from microsoft, but it does not seem to support parameters

Ps. sorry if this is semi off topic, but it still seem rather related.
Best regards..
Mike
