Some of you may have noticed some renewed activity in the drupal6 ports. I'm finally moving the one production site I have from d5 to d6, so it's likely I'm no longer going to spend time maintaining the drupal5 ports.
Migrating mostly works smoothly. The big issue being that you have to redo views manually. Being able to install drupal5 alongside drupal6 is very useful, since you can install both, use backup&migrate to backup your database, and then start the drupal6 engine with the v5 url and do the update. Some modules are no longer supported in d6, or have better equivalents... There is some manual tweaking to do, this is not stuff pkg_add can deal with... Notably: - daterange is dead. Never was updated beyond date 2.0 (and I'm probably still going to update date in d5) - image is dead. Got replaced with imagefield, along with the powerful image cache stuff. (again, probably going to add imagefield to d5). - usernode is dead. Can be really annoying if you have a lot of stuff in there. - imce is dead, but fcke provides similar functionality and is much easier to use. There is some issue as to content access in d6, which one is best, between content_access, node_access, nodeaccess (yes, and those tend to conflict!) Due to the way drupal is built, your existing information will stay in the database, so you can still explore it manually on the database server, and possibly reconstruct missing parts later. For the most part, the update went more smoothly than I imagined. The only painful part was the views stuff, and I've gained a lot of features and tweaks that increase the usability for my users.
