Update 3:40 pm: The upgrade has been completed successfully.
The update contains security, stability and maintainability improvements to the switches.
If you have mounted a TUiScsiBackupDisk on your server, we strongly recommend unmounting it (i.e. deactivating the iSCSI connection) beforehand and leaving it unmounted during the maintenance window to prevent data loss.
Other services using the Backnet network will also experience connectivity disruptions; this, however, only affects small groups of users.
We are committed to keeping the disruptions as short as possible and thank you for your patience.
