I’ve run into a few inquiries recently where folks are having trouble locating all of the add-on goodies for SQL Server 2008 R2 in a single place. Some of this confusion seems to originate from the R2 CTPs and bits & pieces of functionality that had their own trials or early releases as separate downloads.
Go here for the latest definitive SQL Server 2008 R2 Feature Pack with all things grouped together such as remote blog storage, sync framework, powershell extensions, migration assistant, many more.
Enjoy! Best, Mark
