drush site-install to get a Vanilla Drupal8 up and running
From reading the documentation on how to upgrade, I knew that I had to get a contributed module: migrate_upgrade which gives a UI to the
mkdir ~/src/epd8 && cd ~/src git clone --local locald8.git epd8 cd epd8 && checkout 8.0.0 drush si --db-url=mysql://root@localhost/epd8 --yes
migrate_drupal modules that are currently provided in core.
The only modules I feel like I really needed were
drush dl migrate_upgrade drush en migrate_upgrade
mollom because I knew I could simply put in a set of HTML from a Twitter embed widget instead of using the [full twitter module](drupal.org/project/twitter).
So drush handled that for me as well.
I decided that even though this Drupal-7 site uses the blog module from core, that since it was [relegated to contrib](drupal.org/project/blog) and wasn't up to date that I would simply forego the blog functionality and use a normal entity/node type for the "ramblings". So, running the update via drush was as simple as:
drush dl codefilter mollom drush en codefilter mollom --yes
This did all the heavy lifting and converted what I needed in one fell swoop. There were some obvious problems with some of the images due to the fact that I had hard coded some paths in the body of a few posts, but overall the content: nodes, users, comments and basic configuration of content types came through without a problem.
