⌘⌘ Why should i migrate?

• 1.31 LTS went end-of-life in June 2021.
• 1.27 LTS went end-of-life in June 2019.
• its an opportunity to clean and fix things
• Avoid the "Just upgrade!" shame

⌘⌘ What is the effort?

• It Depends ...
• BITPlan and
  Hello World
  report multi-week efforts ...

⌘⌘ Is the migration reversible?

• No its all or nothing!
• really?
• Really there is no proper incremental way
• You'll not like to try so better assume "No!"
