Hi @Elvira1, Thanks for reaching out about this. I appreciate you sharing your current situation!
I’m not entirely sure, but are you currently using Swap Library for this? If that’s the case, it could definitely cut down on the manual work, although it does require you to open the file you’re working on.
I explored but was unable to find a built-in method for swapping libraries for an entire project at once. Additionally, I searched for any plugins in our community that could assist with this task, but have not found one yet.
You might already know but you can check the swap library details including how does it work and preparation process from here:Swap style and component libraries
You can also watch the corresponding YouTube here: Swap style and component libraries
I hope this information clarify a bit. If I have misinterpreted anything, please inform us. Furthermore, if anyone in our community has any other recommendations, please share them here.
Thanks again for reaching out.
