How to transfer a pdf and it's metadata in folder from a collaboration site to a myteam site library?

We have tried transferring the pdfs multiple ways:

1.) using windows explorer - which works but the metadata is not preserved 2.) moving pdfs one by one - not efficient enough 3.) tried transferring by using content and structure - when I selected the folder I wanted to transfer it said move is not support for lists and folders.

I want to know if there is another way we can move pdf documents saved in a folder from a collaboration site to another site all at one without losing it's metadata when transferred?
