Well, after much testing, and with a bit of sadness, the best way for me to migrate from a Craft-hosted website to a Micro.blog-hosted website will be to export each document to Ulysses then publish to Micro.blog while back-dating each post. The good side is that I’m going to update and rework most of the content. Not all posts might make the cut, though. I’ll continue using Craft-hosting solution for the best and richest content visualization.
