Re: upgrade 8.0.3 -> 8.2.4

Thanks all. The only problem that I had was the unicode stuff, and that needed cleaning up anyway so I'm not too worried. I've at least managed to get this database on it's own tablespace ( hint: when outsourcing development to a company you never met, you may well be paying a bunch of schoolkids to learn some technology! ), although moving it out of the public namespace will take a major rewrite of the application ):

All is owrking fine so far, and the poor frontend server isn't suffering quite as much as before.

Cheers, Steve
