Hello All, In my company, we are sill using 5.1 usr3. My boss asked me to a most recent version. Because of license issues, i need to update first to 5.1 usr6 and then to 6.1x. but i have no idea about the way to do that. I don't know if i have to replace the old files bu the new one, if i have to write some setup scripts ... What about our simulators ? To make short a long story : Help me please to do correctly the update! (bindkeys, environnment, setup, simulators ... and so on) Any help would be very appreciated ! Thanks and regards, bu
