Most of the information I have come across about migrating from Drupal 6 to Drupal 8 is about migrating content, however before tackling this problem another one must be solved, maybe it is obvious and hence understated, so let's spell it out loud

There are cases when you want to export some content from a website, in order to import the same content at some later point into a similar website in an automated fashion.

I've added an IPv6 Greeter block on ao2.it in order to greet the IPv6 users, and to inform the others about the existence of the new protocol.

Added short URL links to ao2.it, you will find one at the end of each node content.
