Yesterday I realised that this blog is close to 9 years old. I think its first version was based on Drupal 4.x and I remember I kept it installed in my own Linux server at my shared flat room under a 'homelinux.org' subdomain.
After attending Barcelona Drupal Devdays, where many of the talks debated about the upcoming features of Drupal 8, I thought it was time to upgrade my rusty Drupal 6 website to current stable version, Drupal 7. Since soon or later I must upgrade a couple of other Drupal 6 websites, I considered it was worth trying it first in my own personal weblog.
Below I detail some of the problems and difficulties I encountered during the update process. I imagine most of the stuff is related to the fact I've been upgrading for such a long time and because of using certain extensions. Anyway, I hope this can be helpful to other people.
