Difference between SSAS 2005 and SSAS 2008
I went through a pretty thorough 2008R2 training a year ago. It wasn't radically different from 2005, but it was different enough that you're going to face quite a bit of frustration when you can't do things in 2005, or the things you want to do are done differently. SSAS has been changing quite a lot over the last several releases. This is the list of changes between 2005 &amp; 2008, and it's not small. The new designers are the things that are going to cause you the most pain.
