SHOW time!!! 1, if you upgrade from SQL2008 to sql2008r2 then you can only select the left "install" corresponding to the right "from SQL SERVER 2000,sql 2005 or SQL 2008 Upgrade" This option to upgrade.

Only when you have more than two instances installed on the server can you hear the word "instance" more. But "instance" is definitely the place to be known in the Learning database process, select the instance you want to upgrade. The next step would be fine. 8, previously installed components (component) will appear here, no tube, before, and now of course, have to, close your eyes click "Next" Bar! 9, because is the upgrade installs, so your previous instance name is what, here still is whatYou.
