Upgrade from Drupal 6 to Drupal 7

After a lot of preparation, I've finally upgraded this site from Drupal 6 to Drupal 7. The DEV upgrade worked out well enough that tonight I upgraded PROD.

Here are the main Drupal guides to use:

In the end, it's the README.txt from the D7 install tarball that you have to use for detailed step by step instructions. You'll want to make your own customizations to the steps of course.

At this point the only minor annoyance is that a couple of the modules I use are only in Beta in D7, even though D7's been out for months already.

Remember: tarballs and mysqldump are your friends. Use them often. You can never have too many backups during a major upgrade.
