The document discusses how Salesforce transitioned over 70 writers to a new authoring tool, Oxygen Author, in a single day with zero downtime. It describes how Salesforce managed such a large change by extensive planning, working out issues in advance, clear communication, and training to ensure a smooth rollout and transition with no interruption to their documentation work. The speakers, Steve Anderson and Deepa Aswani from Salesforce, led the project and will discuss their process and strategies for managing the transition.
