1.Install the TIU site. It automatically will create the SQL Express database and you will not be asked for configuring database or set up credentials. ( by default they are admin, admin)
2. Then, go to the TIU website root and get the database ( Sitefinity.mdf) form the App_Data folder.
3. Create a new database or just attach the existing one under SQL server 2008.
4. Finally, change the connection string in the TIU website web.config file to point to the database.
I hope this helps.
