Troubleshooting and other upgrade resources

Use this information to troubleshoot post-upgrade issues and learn more about other aspects of ServiceNow's upgrade process.

Evaluate log data

Performance and operating information is available in the system logs, which offer an excellent source of information for evaluating the inner workings of a ServiceNow instance. Use this information to help resolve as many errors as possible. To access the log data, navigate to System Logs > System Log > Errors.

Note: Not all errors in the error log are results of your upgrade. Error messages are often present in pre-upgrade instances, and many of these messages do not affect users or performance.
