Upgrading to breezy from Hoary?

[Henning Kilset Pedersen]

Hello.

I downloaded the Breezy daily build yesterday, and am currently running 
Hoary.

I was a bit surprised to see that there is no upgrade option in the 
installer program. Is there a way to upgrade from hoary to breezy that 
is non-destructive? Can I just substitute the sources in sources.list 
with breezy sources, close my eyes and type

    # sudo apt get upgrade

??

Or is there some other way I'm not familiar with?

Regards,
Henning
