I'm trying to move a large amount of files from one CDN to another. I know that they have a very high-speed connection to each other, so what I'd like to do is connect them directly, but the only protocol I have access to with each is FTP. Is there any way to log into the current CDN and send their files to the other FTP? It seems like it should be possible, I just have no idea how to do it.
FXP: see Wikipedia article. Powerful FTP clients are capable of doing this. From protocol point of view it's trivial.
BTW this question is probably offtopic here.
