OnlineCSU WebCT and access to the library databases have not, and should not, be affected by this change, as both are controlled from separate servers.
Here is the official message from campus IT, sent Tuesday:
The Campus Pipeline to Luminis migration will begin at 5:30 PM on Wednesday, August 3.
Access to the MySCSU portal, email, WebCT, and personal web directories (U: drive) will not be available at that time. Access to all services, except the MySCSU portal, should be available by 12:00 midnight. The new MySCSU portal will be available by 12:00 noon on Thursday, August 4.
Thank you for your patience during this migration. We hope you will enjoy the look and feel of the new MySCSU campus portal, which will still be available at the URL myscsu.southernct.edu.
