Has anyone checked to see whether there's any practical reason (i.e. $$$) to migrate at all? Disk is pretty cheap these days and HSM is a notable pig in most shops, ours included. I question the value of spending CPU cycles shoveling bits from one cold place to another - typically in the same array. If it were mine, I'd leave it spinning on disk until it was so old it had cobwebs on it. Then if I cared enough about the space, I'd shove it out to a big fat tape vault and forget about it. YMMV.
