Move documents from one library to another library with managed metadata columns

Issue: Moving one folder which contains hundreds of documents from one library to another in SP Online

I am having a folder which contains two sub folders. Out of two sub folders one sub folder is having unique permissions. Both sub folders are having 100s of documents. Now I want to give a way to end use to move the top folder to another library which contains same content type. I am having columns to documents like Managed metadata, lookup, Choice. When I try to move the parent folder with MoveTo function in modern sites, everything is moving fine, but destination documents are not having managed metadata values. Also i want to remove the unique permissions on the sub folder after migration. Is there anyway to achieve this OOB or workflow solution?

Questions:

1. How to move managed metadata column values to another library?
2. How to delete unique permissions on folder after moving to another library?
