How would you upgrade it with minimal downtime?If minimal downtime is what you want, then you have to get another box - install it with the OS of your choice and verify it works, mail it to the US and install it near the old box, stop all the services on the old box, migrate all the data over and start the new one. If done properly - and depending on the amount of data and what can be copied before stopping the service - you'd be looking at 30 minutes to two hours downtime.
Last time I did something like this it took me about a week to get the new machine to work the way I want (after it was installed on the rack), and then about 15 minutes for the move - of which, of course, only the 15 minutes were actual downtime.
