Thanks. Well, yes, it's not supported, but I think it's still a legitimate question, not a troll or some negative remark, so I wanted to know what was objectionable. I think I can intuit the answer to that from other replies - some people think "just upgrade OS FFS" is automatically correct no matter the circumstances. Anyway, the author answered really helpfully, for which I'm grateful.
