Today I came across this error: “An Operations Manager Agent and Operations Manager Server of different versions are being installed, this is not supported. Please make sure you install same version of these components”.

I was trying to create an OpsMgr 2007 R2 database on a SQL server. This SQL server was already monitored by another management group running OpsMgr 2007 (not R2). Agent upgrade was not an option (at least for now) and therefore I used the DBCreateWizard tool from support support tools folder located on installation media. This worked just fine
