Upgrade Issues (Part 2)

AX 2009 AOS does not start

There are multiple reasons why the AX 2009 AOS will not start the very first time. One reason may be that some maggots have modified system classes like Info, Sys* etc. Fortunately the AOS posts its pain to the windows event log. In the case of modifications on system classes the AOS posts a stack trace to the event log.

    1. Review the event log errors
    2. Identify the poison modification
    3. Remove the modification in the source system
    4. Copy the cleaned layer file
    5. Delete the .aoi file
    6. Start the AOS
