Hello @LoganIN and welcome to Microsoft Q&A.
There is an option for preserving the metadata you mentioned. See Here. This option applies only to binary dataset because other types allow mapping, which can change contents, and make the metadata invalid.
When you configure source as Data Lake Storage Gen1/Gen2 with binary format or the binary copy option, and sink as Data Lake Storage Gen2 with binary format or the binary copy option, you can find the Preserve option on the Settings page in Copy Data Tool or on the Copy Activity > Settings tab for activity authoring.
Thanks, Martin
