I am importing a D7 site into Backdrop. The existing blog posts are aliased as node/ and not blog/ and I want to be able to reference them in a visibility condition in my layout, but there doesn't seem to be an option to do that. visibilitycondition So, I guess I will have to bulk delete the existing aliases and regenerate using the new pattern. But then, I think, I will lose the existing links known to search engines, won't I?
