Explore a more stress-free approach to Drupal major version upgrades.  We will discuss scripting your upgrade in a way that allows you to quickly re-run the process for multiple test passes.  

• Prepare a backup ahead of time, or have one created on the fly as a part of the process.  
• Automatically deploy a staging site at each upgrade junction, and allow for interval inspection.  
• How to handle situations like abandoned modules, modules without an upgrade path, and other difficulties.  
• Coordinating the testing, deployment, and training with your client.
