Upgrade from 2.0.3.1 to 3.0.2.0

Hi,

I've done a ton of searching on these forums and the closest thread that I've found that addresses my issue is here.

Considering that is over a year old, does anyone have an updated resource that they can point me to so that I can achieve the upgrade? Similarly, is there an easier workaround that someone might suggest? Is it easier to just do a clean install of 3.0.2.0 and import backed up content from 2.0.3.1?

Thank you in advance.

table structure changed, some table names even changed not tomention the columns.you need manual upgrade with human in fron of pc not a script with automated tasks:)
