Collect the following data immediately after the upgrade fails:
- A Minimum Escalation Requirement (MER) from the ePO server.
- The entire ePOUpdaterLogs folder in C:\ProgramData\McAfee\ePolicy Orchestrator\ePOUpdaterLogs. This folder contains all Cumulative Update logs.
- The entire McAfeeLogs folder in %temp%\. This folder contains the complete set of installation logs for the ePO server.
NOTE: You must be logged on with the same user account that ran the upgrade for the %temp% variable to work. Otherwise, you have to navigate to the user temp folder for the profile that launched the upgrade to find the logs.
- What version of ePO are you attempting to upgrade from and to?
Justification for data requested:
- A MER from the server is needed if the logging alone does not fully explain the issue. Many times, other data that is included in the MER is required, including but not limited to:
- Environmental variables
- Running processes
- Other point products installed
- Exact version numbers for the agent, ePO, or DLLs
- The MER does not always capture the entire set of installation logs so they should be captured separately. For example, if you ran the installation while logged on as UserA, then ran the MER while logged on as UserB because the installation logs are in the user's temp folder, the MER will not capture these because they will not be in UserB's temp folder.
