Tool for Upgrading to SQL Server 2008

In this post i will let you know the tools provided(only 1 as i know) for upgrading your SQL Server 2005 instance to SQL Server 2008.
Upgrading from the previous version of SQL Server to a newer version is always a challenging task for a Database Administrator. In order to improve the SQL Server 2008 upgrade experience, Microsoft introduced a free tool called SQL Server 2008 Upgrade Advisor (SSUA). This tool basically does the analysis of installed components of the earlier SQL Server versions, and generates a report which has details about the issues that need to be fixed either before or after you upgrade to SQL Server 2008.
