This presentation provides an overview how CQ was implemented at ESO. It reviews the approaches and concepts that were chosen, making sure that all operational and authors’ requirements were satisfied, and how it was achieved to have an implementation and rollout of CQ5 in only three months. Also, the presentation will provide an overview of the architecture of the Day CQ system at ESO and its marriage with pre-CQ system. Rein Warmels, Astronomer & Christina Garcia de Juan, Management Consultant, European Southern Observatory

Approaches
& Methods
• Basic Project/Implementation Plan
• No large documentation efforts: TWiki-based
• Rapid Prototyping – Continuous testing on users
• Split the migration in packages
Be Pragmatic
• Short communication lines
• Regular meetings
(Project Team, Steering Committee, Users)
• Make future authors/users part of the project

Migration Iterative Cycle - 3 Months
• Content Analysis and Migration Package Definition
• Migration Package Tuning
• Creation of mirrors (curl commands)
• Automated Migration: Parsing HTML
and mapping site structures
• Agreement: migration in 95% of the site
content to Rich Text Edit Component
• Risk: Performance on client side
• Quality Check
• Training and additional Support
• Configuration and Performance Check
• Deployment
• Migration Package Going Live
