„Every non-trivial upgrade should be approached as a relaunch.“

„The primary challenge is not development but communication and project management.“

„Bring time. And space.“

„Expect everything to break!“

„Don't experiment, document.“

„Write your code as if your own kids will inherit the code one day.“

„Write upgrade-steps.“

„Divide and conquer.“

„Don't try more than two new things at once.“

„Use the Help.“
