Hi Jeff ,
Have you shut down the domain before starting upgrade process ?
Also check log files under ../user_projcts/upgrade_logs .
The domain has been shut down...and this is a domain with ADF installed
I'm having the same problem. I have an existing domain in WLS 10.3.5 and I have just installed WLS 12.1.2. Is it not possible to update an existing domain from an earlier version of WLS?
I too had the same issue...our domain was version 10.3.5. I couldn't find detailed upgrade instructions for 12.1.3, but I did for 12.1.2 at the following page:
Based on this Roadmap, the Reconfiguration Wizard is the tool that should be used to upgrade a domain based on Weblogic 10.3.1 or later. It can be found under the Programs menu under the new Oracle program group created by the installer (i.e. Start->Programs->Oracle->OracleHome->Weblogic 12.1....->Tools->Reconfiguration Wizard).
After following the prompts and minor additions, the 10.3.5 domain was successfully upgraded.
