Yesterday I started converting a bunch of Visual Studio database projects (.dbp) to projects for Microsoft® Visual Studio® 2005 Team Edition for Database Professionals (.dbproj).
The easiest way to accomplish this and get immediate benefit from the new features of VSTS DB Pro is to make sure you have a fully up to date database, then create a new DB Pro project and use the Import Database Wizard to suck in everything from the database. A script will be created for each and every scriptable object in the database.
After having done this the Schema Compare functionality is great! Can believe I ever did anything with databases without having this tool!
Updates for DB Pro seem to come pretty fast, CTP 2 for Service Release 1 is available for download already. Watch the DataDude blog to keep informed on DB Pro.
