Database Upgrade to SQL Server 2008 Tools and Approaches

This is one of the best article to read about Tools and approcaches to upgrade production servers  to SQL Server 2008.

SQL Server Technical Article:
Performing an upgrade is a complex and often risky project. A successful upgrade can provide an organization with a modern platform for development and production. An unsuccessful upgrade can cause lost time and money, and it can create a bad perception for the future.
This paper documents approaches and tools that can help DBAs and developers to achieve successful and mostly painless upgrade of SQL Server databases from Microsoft® SQL Server® 2000 or SQL Server 2005 to SQL Server 2008 (or SQL Server 2008 R2).
In the methodology this paper discusses, a SQL Server workload is captured on customer production environment, and then this identical test workload is run on the old and new versions of SQL Server in a test environment to compare performance and isolate any problem queries. For this approach, we use components from the "RML Utilities for SQL Server" set of tools.
