In this directory, you will find an upgrade_supervisor_database
program from your operating system.  This program will prep your
supervisor's database for the upgrade to 6.5.  

Upgrading to Qube supervisor >= 6.5 (from a version < 6.5) makes
changes to the database tables for all jobs in the database.  For
farms with thousands of jobs, this can take a *VERY* long time - from
minutes to an hour or more.  We *strongly* recommend that those
customers having several hundred or more completed jobs in their queue
run this upgrade_supervisor_database program PRIOR to installation.  This
command-line program can be run on an active farm with little or no
impact on performance.  Once complete (which may take from minutes to
hours, depending on queue size) continue or restart the installation
process.  During install, you may get a warning message about the need
to run this pre-installation program.  If you have already run the
program, ignore it and continue.

If you have less than a few hundred completed jobs in your queue,
there is no need to run the upgrade_supervisor_database program.

If you perform a 6.5 supervisor upgrade on a busy farm without first
running the pre-installation program, you MUST allow the install to
complete - which could take from minutes to hours with little to no
feedback.
