I’m following the instructions at “The Importer” to import posts from my current Octopress blog to Ghost. Despite specifying the import
.json file correctly, the import was failing with the error, “Detected unsupported file structure”.
It turns out, the version specification for Ghost import files changed between 1.x and 2.x, it now requires semantic versioning. Changing the “version” from
"2.0.3" fixed the issue, and my posts were successfully imported.
Just posting this hear in case anyone else runs into this mysterious error.
