Hi Frederico 👋
Great question! I’d recommend using a plug-in like Symbol Swapper to redirect connections from the original Library to the Master in Abstract. We actually have a Help Center document that will walk you through the necessary steps here: https://support.goabstract.com/hc/en-us/articles/360001392632-Importing-Sketch-Libraries 😄
Let me know if you have any further questions!
