If the Cause of the Failure Is Unknown

If the upgrade process fails again, and you cannot determine the cause of failure look here for the location of the error log file.

By default, the log file is located in $SYBASE/$SYBASE_ASE/install/<servername>.log.

Check the error log file to find out when and where the upgrade failed, and contact Sybase Technical Support.
