For the Symfony2 users out there, a site has been started to help you run through a checklist and prepare your application for deployment, the Symfony2 Checklist. It's a set of things you can cross off by clicking on them to ensure you're set to go when the right time comes.

The list includes things like:

• Check the production server
• Customize error pages
• Use Doctrine cache
• Configure Monolog
• Protect your forms

It's a good base list to start with, but there's other things to consider (some more app-specific) that need to be thought through before deploying. If you have others you'd like to see added, you can always fork the repository and submit a pull request with the updates.
