When I run the installer I get this?--- Do you mean AR installer to upgrade?
Oh, no. Sorry!
The AtriuM CMDB installer
The AR server is already upgraded on this system.
if you want to upgrade CMDB on staged system (copy of Prod system with old version), it will check for existing CMDB config files during upgrade?
Probably because installer is running in upgrade mode instead of new installation as AR is done with upgrade mode.
It actually isn't a copy of prod (that would be an in-place upgrade, correct?). It is a copy of filesystem with exact same version and patch level as the production environment - but only the AR Server. Then the production database is restored on this system and server references (in db) changed.
I started with "Upgrade", but the installer isn't too happy about the "Install" mode either since it complains the product is already installed (true if you look in the database).
Oh, never mind. I am real dumb. There was a stub for /app/bmc/AtriumCore from a botched attempt. After I removed it this problem disappeared.
