Upgraded to 2008.2r2, all works fine except the nsm_setup utility is passing a flag to the setup script "niBYPASSMIGRATION" that is no longer supported. I can see it is valid for the 2007r2 and 2008r1 versions (still got the scripts in the /var/install directory) but not the latest.
Not the end of the world as the configuration can be changed using other means, but it is a cause of irritation and makes me wonder if the upgrade has failed in some way? Or is this the same for everyone else?
