Will upgrading from SQL Server 2008 to SQL Server 2008 R2 affect any existing databases?

Question

I'm amazed at ReportBuilder 3.0. This might be just what I need for my job. I haven't thoroughly checked the differences between SQL Server 2008 and its R2 version so I don't know if upgrading would be a hassle.

Answer 1

SQL Server 2008 to R2 is quite minor. Especially compared from SQL Server 2000, say.

Be warned: once your databases are upgraded, they can not be restored on an install of an older version. It's a quite common question on StackOverflow and ServerFault...
