From David Sieser and Kevin Zibluk of Information Technology:
On the weekend of Dec 2nd, the university Information Technology team
will perform a major upgrade to our Banner system. As a result many
administrative functions will not be available during this time.
Therefore, all transactions related to registration, payments,
financial aid and many other administrative activities will not be able
to be performed both online and on-ground. We thank you for your
patience during this time.
It is anticipated that the Banner system will be brought down on Saturday, Dec 3 at 12:30 A.M. and won't be available until Monday, Dec 6 at 10:00 A.M.
If I've understood this properly, the upgrade will affect the staff side of Banner, so students and faculty using the web interface should not see any changes after the upgrade.
