I saw this article on the upgrade :
http://technet.microsoft.com/en-us/library/dd335967(v=office.12).aspx
questions :
1. for updating the .NET framework, it says to execute sqlserver installation setup.exe
so the sqlserver installation will itself detect the need to updating .NET and automatically open the .NET framework setup wizard so that the needful can be done?
2. for installing the hotfix for windows how to start the installation wizard for the hotfix? where do we find the program?
3. for the sqlserver upgrade, point 9 says 'select sqlserver instance to upgrade' and point 11 says 'select database instance to upgrade'. what is the difference between the two?
btw before running the upgrade are we supposed to run sqlserver 2008 upgrade advisor to pre-empt any pending issues?
and btw if we were to load or attach a 2005 database backup into a 2008 sqlserver it would automatically upgrade the database during the restore?
and btw2 what is the common strategy used to rollback to 2005 if something goes wrong?
appreciate the feedback.
