I posted a tweet about this last week and it was suggested that I put it in the forum.
I did the upgrade from Drupal to Backdrop about 7 months ago. The Backdrop site is not in use yet but will be by the fall so we are still adding content to the Drupal site. While working in Backdrop I've made numerous changes that make updating the site with the Drupal database will not work. Now I have over 50 blog posts, including photos to move into Backdrop. I've been doing this manually when I have the time. It's kind of like treading water.
It was mentioned that I could probably use Feeds to automate the process. Keep in mind that I don't have access to the code of the Drupal site. I need to ask to have modules installed and to get backups. So what would I need installed? I've wanted to ask our vendor to install Backup & Migrate in the past but I'm not completely sure they would do that but I could try. The alternative is that I keep up the cutting and pasting.
