Single Database Custom Icons
As the database name has been modified, any code referencing the old database name will need to be updated
In the case of Custom Icons you can check these by accessing System > Configuration File Maintenance
In the Find field, type CustomIcon

Please Note: If there is an error in your code, it will show up when a user attempts to access a maintenance screen (e.g. Current Student Maintenance)
