Move/Copy attachments

Move/Copy attachments

I am attempting to put an attachment from one request to another through the v3 API and using powershell. 

I know how to find the attachments on the original case but not sure if I can simply use the attachment information from one request and add it to another request or if I would need to download the attachment from one and reattach to another request.

anyone able to point me in the correct direction would save me a lot of time.
