I'm migrating the Legroom website and all related services to a new server. As part of this process I've re-implemented Drupal from scratch. I'm basically using this opportunity to re-baseline on the current version without all the old content and customizations I've been carrying forward since Drupal 4. I exported and imported all primary content from the old site, but none of the forum content, comments, users, etc.
Some functionality depending on customizations from the old website won't display correctly, but all content should be there. I've also switched to a customized version of the new default Olivero theme, which I've made less terrible by removing a lot of the wasted whitespace. I'm also using the Olivero Dark Mode subtheme to enable dark mode for the site, which is a nice new feature.
I hate to lose all the old content and functionality, but the constant changes by Drupal with each upgrade have made things pretty fragile after 20 years of upgrades. Plus, I obviously don't update the site much at all any more, so this felt like the right time to make a pretty clean break, re-baseline, and simplify the maintenance project going forward.
