We are in process of developing strategy to migrate from 2006.0.8 to 2008.2. Did you migrate from older newScale version to 2008.2 or did you implement 2008.2 from scratch? To know your experiences would helps us a lot in our migration to 2008.2 version.
We migrated from 2006.0.2 to 2007.1.3 back in Feb. This required an interim upgrade to 2006.0.7, which you shouldn't have to do. Then, because of business needs, we went ahead and upgraded to 2008.2. The 2008.2 was much easier from a newScale perspective, though we also upgraded to Weblogic 10.3.
