We once had a consultation with a Drupal Agency when we moved from D7 to D9. They explained to us that "blt artifact deploy" can be used to fill a git repository that is then copied to the server for hosting using CI/CD.

With BLT not being maintained anymore, what's the successor for this kind of workflow? Is there a replacement to handle this? Should it be done on a per project basis and artifact deploy isn't a valid approach anymore?

Would like to get some insight on how others do this and appreciate any feedback or hints to tooling or workflow to learn.

As the subject says, I'd love to edit some theming colors to recreate an old site stuck at Drupal 7, the theme itself is Bootstrap Business and while this was part of the theme back in the day those options no longer exist in the current version for D11

What is the best/recommended way in 2026?
