Sketch to Figma Migration - connecting components to existing library

Hi there, we are moving a project from Sketch to Figma. We have already the design system in Figma with all the components ready to use. The question is how can we connect components from project file to existing design system from a library. The only way I can see right now is replacing the existing components with ones from the design system. But is there a way to skip this manual work?

@Dima2 - I have the same question, did you get a response or figure out how to do this without a lot of manual work?
