It seems as if I managed to get the upgrade right. There are still some plugins that I need to check but I also take the opportunity to reconsider which plugins I really need for this blog.My old Prosumer theme would not work with the new version of WordPress so I have changed to a modified version of the xMark theme. At first I was annoyed about the forced change of theme but now I like the new one better. The new look is even cleaner than the old one

I do look forward to use the new tag feature, I have started on this post. Older posts will get tags in due time and if needed.
