Hi Kwohlgemuth
Firstly thanks for replying. An update on where Im at
On reading your post I came intot the office this morning and the first thing I did was download the HP 5.5.0 GA ISO to use instead of the HP 5.5u1 ISO. When I use this one the upgrade happens without any errors or compatibility issues. After pushing out 5.5GA, there were a number of critical and no-critical patches to install, one of which was Update 1..... test host is now at 5.5 Update 1 with all patches installed.
Im not sure who updates the custom ISOs whether its VMWare or HP but looks like somebody messed up with this driver in the HP 5.5u1 custom ISO.
Thanks
