About the Siebel Upgrade Log Files
The Upgrade Wizard writes logs that provide detailed information on the upgrade processes and they also list all errors. The Upgrade Wizard writes the logs for a process to the following directory by default:
Windows: SIEBEL_ROOT\LOG\process
UNIX: $SIEBEL_ROOT/log/process
where process is the name of the upgrade process
you have run, for example, upgrep_dev_782 or prepare_for_production_upgrade.
The process directory contains the following subdirectories:
Output. Directory containing the Upgrade Wizard log files
State. Directory containing the state.log file
The output and state directories are automatically archived on
subsequent runs of a process that completes successfully. (The names
of subsequent log directories are appended with _1, _2, and so on.) To preserve disk space, periodically
delete or save log directories to another location.
