Hello,
Upgrading from OnTime 2007 to 2008 will require a database change. You will also need an OnTime Admin account not using Windows Integrated Authentication.
All your data should get upgraded without a problem and all your Work Logs Work Flows etc. should remain. New features will become available. You will need to upgrade all clients of OnTime to the new 2008 version (Web Client, Customer Portal, E-Mail Queue Service, Remote Server, Windows Client & OnTime for VS.Net)
For OnTime Windows Client you will need to reconnect using the OnTime Database Setup tool

Let me know if you have any other questions.
