<suitecrm-root>/upgradeWizard.log
When an upgrade fails or produces unexpected results, these log files are the first place to look.
The primary upgrade log. Written by both the Upgrade Wizard and the CLI upgrade methods.
<suitecrm-root>/upgradeWizard.log
This file records each step of the upgrade process and captures errors encountered during file operations and database changes. Check here first for any failure message.
The main SuiteCRM application log. May contain errors related to the upgraded application that surface after the upgrade is complete rather than during it.
<suitecrm-root>/suitecrm.log
When using the CLI upgrade, you specify the log file path as an argument. Check the path you provided to the command.
For the robo method this is the <logFile> argument. For silentUpgrade.php this is the second argument passed to the script.
If the standard logs do not contain enough detail, you can increase SuiteCRM’s log level temporarily:
Navigate to menu:Admin[Diagnostic Tool] or edit config.php directly.
Set logger_level to debug.
Re-run the operation you are investigating.
Reset logger_level to its previous value (fatal or error) afterwards to avoid excessive log growth.
