I just upgraded the blog to version 1.6 of BlogEngine.NET, using the incredibly useful guide from David Wynne.
Two things he missed though: Remember to change your CSS file as described in the ‘official’ instructions (change #widgetzone to .widgetzone, and #widgetselector to .widgetselector) and to be sure that any changes you made to your web.config file are copied across with the rest of your site (default blog provider, database connection settings, and the like).
If you did change to the database provider for your blog, there are scripts to manage the upgrade (especially since Blogroll is now stored there!) in the setup folder.
Since you can see this, I made it work! Hooray!
Now to mess around and see what’s changed… and finally get that BlogRoll working!
