I’ve just successfully exported 4453 posts from my Micro.blog hosted blog and imported them into a Day One journal using the macOS Micro.blog app.
The whole process took about 3 hours, most of which was taken up by the downloading of all the blog images.
The Day One journal entries look very good - much better than a lot of those I have been crossposting from Micro.blog to Day One using IFTTT. They would often lose some formatting and only import one image from multi-image posts.
I paused the Day One sync service during the import process - now I’m just dreading turning it back on. I know it’s going to take a very long time to upload all these posts and images to the Day One servers and while the process is underway my (already poor) broadband service is going to slow to a crawl.
Now I just need a way to incrementally export new posts from my blog to Day One. I’d rather not go through the process of exporting and importing thousands of posts each time!
