Good day! I have a task to upgrade my ManageEngine Service Desk from version 9.3 to the last. I left instructions from the  official site and here from this site. I managed to upgrade to version 9400. After the next update to 9426 or 10000, I constantly got an update error "Sorry, your upgrade from 9400 to 10000 failed. Send us the log file for further analysis.". Where can I see the event logs and find the reason?
