How to duplicate a project & design system and be linked?

I created a new account and duplicated the production and design system, from my old account, to the new account. The problem is that the duplicated production is still connected with the original design system and not the duplicated one. How can I link the duplicated production with the duplicated design system without having to link every single component with the duplicated design system again, that would take 2 weeks.

See image.

Use the “Swap library” feature.
