As I read [1], sftp.File.WriteTo() writes the instance it's called on
to the supplied writer (implementing io.Writer), so calling
dstFile.WriteTo(srcFile)
is like saying "Hey, dstFile, please write yourself to srcFile",
which is the reverse to what you're apparently after.
So my take is that you should use
io.Copy(dstFile, srcFile)
instead.
