As you already know, Pelican is not a content management system like WordPress, it is a Python static blog generator – there is not database, nor a web interface. We use reStructuredText or Markdown to create the posts and pages and the entire content is flat-file based and managed by the CLI. This type of storage gives you the chance to manage the posts and if necessary to migrate them.
