Copy documents from source to destination sharepoint libraries while preserving the original documents properties such as Created,CreatedBy

Question

I am working on 2 sharepoint projects, which are 2 separate sharepoint farms that are inside the same domain (Old farm & New farm). Now inside the old farm we have 20 sharepoint documents libraries, and we want to COPY all the documents from the old farm to the new farm. but the point i am asking about is that i want to COPY the documents while preserving their original properties including :-

• Created
• Modified
• Created BY
• Modified BY
• Title & Name

now i am not worried about moving the libraries themselves and their settings, but rather i am worried about COPYing the documents. so currently i did the following:-

1. on the new farm i added 20 new documents libraries, which mimic the old documents libraries. where i define them to have the same library name and settings.
2. now i try to manually COPY the documents from the old libraries and PASTE them inside the new library, but i have noted that the created date will be equal to current date (date of the PASTE) instead of the original created date.

so can anyone advice what are the appraochies (using power-shell or other means) that i can follow to COPY the documents between the 2 sharepoint farms? so is there a power-shell script that i can use to move the documents?

I have the following 4 points to be mentioned:-

1. some libraries have the documents organized in folders.
2. the two farms have different permissions. so the site admin on the source farm can not access the destination farm and Vice versa. now if this is a major issue, i can grant the admin the related permission on the second farm during the move operation.
3. both farms are sharepoint 2013 on-premises.but they have different build numbers.
4. now in sharepoint each document library can be accessed from a web url such as http://servername/sites/HR/HR Documents/ and this can be opened as a folder inside the machine also.
