Before I upgrade to QuickBuild 10, I want to know the existing version of my console and agents. That way, when I upgrade, I can check again to see that everything was upgraded. The browser shows me the version of my console. But, I don't know how to get the version of my agents. I see an attribute called wrapper.version. Is that what I should be looking for? In addition, if I back off the upgrade to 10, will the agents automatically back themselves off to interface properly with QuickBuild 9.x?
Release information including version is recorded in file /asset/release. When downgrade QB10 to QB9, build agents will not be able to connect to QB9 as some bootstrap libraries have been changed when upgrade from QB9 to QB10.
