Debian stable to testing upgrade

[John Wheat]

To do this upgrade should the procedure be done from a console with no X 
server running or does it matter these days? I found release notes for 
Sarge to Etch that mentioned I should upgrade the kernel prior to the 
dist-upgrade would that still apply in Etch to Lenny. I am not concerned 
if the whole install gets hosed as Etch is installed on a drive I use 
only for testing purposes .  I just want to  be sure the  procedure is 
done with the smallest chance for human induced error as possible.

Thanks,
John
