I attempted an upgrade (v5.6.8 to v6.2.8), ran into some problems which I now think I've resolved. Now I want to know the best practice for making another upgrade attempt. Do I simply re-execute '<root>/Install/install.aspx?mode=upgrade'? Or do I need to get the site back to some initial state? For example, by recopying the contents of the upgrade package to the site.
FYI: I'm attempting to get my customer's site to the current DNN version following the DNN's 'Suggested Upgrade Path'.
