    Hi Sajad,

    to list the history of the kernel fileset may be a good starting point.
    lslpp -h bos.mp64

    In addition to Markus' answer, you can find files of a version older than the date returned by the command 'lslpp -ha bos.mp64' in the / etc directory by 'ls -lt /etc'.
    Hopefully there is a backup of motd that will be able to show the exact version that was installed. Otherwise, you should be able to find old rc.* files with the AIX version on the header.
    Best regards

    Check the headers of common configuration files like crontabs, you might see references to the original base AIX version still in the headers.  I know I have AIX 7.2 systems that still show AIX 5.3 in the comments of roots crontab.

    Hello Sajad,

    I have 2 AIX boxes : one in fresh 7.2 installation, and one originally in 6.1, then migrated in 7.1 and finally 7.2.
    By the 'grep "# bos" /etc/*' command, you can trace version history.
    In file headers, bos61x, bos71x otr bos72x give information on the progress of AIX versions : bos61x for AIX 6.1 and so on.
    I cannot tell you what is the meaning of the last character (x) in bos61x ...

    Hope that can help you :-)
    Best regards

    Isn't the instfix database populated only by service packs? I know it
    doesn't include all the fixes of the OS at install time. Maybe you can
    leverage the APAR list?
