I dont think you can with the iso file

if you want to use that you need to reinstall

the other option is to run

update-manager -c


then tell it to upgrade to 810

then do it again to 904

it takes hours

I just reinstalled and it was much faster than upgrading to 810

I am now trying to find out if its possible to use all my old settings and packages from 810
