Migrating your Wordpress site content to Ghost
Partially due to the founder of Ghost being a prior Wordpress developer, it has been made quite simple to import your Wordpress content into Ghost. Thankfully, a plugin has been developed to import your Wordpress post content into Ghost. Within minutes, all of your Wordpress posts will be imported into your new Ghost installation.
Exporting your Wordpress postsAny exporting of your Wordpress posts can be done within a simple plugin. Unofrtunately, a few things may not be exported:
Any files that are not images will not be able to be imported. This includes things such as PDF files. Of course, you could always add those in afterwards.
Any linked content using shortcodes would not be imported.
As Ghost does not natively deal with comments, none of the comment data will be imported from Wordpress.
custom post types or pages are currently not exported by the tool.
Installing the Wordpress plugin to export Wordpress post data to Ghost
First, you will need to locate the Ghost plugin for Wordpress. This can be done quite simply as the Ghost plugin is available within the Wordpress plugin database. To do so, click on Plugins on the left side of your Wordpress dashboard, then on Add New. From here, search for the word "Ghost". The first result should be the one that you are looking for.
Once you have located the Ghost plugin, click on "Install Now". Wordpress will then begin your installation. When the plugin installation has completed successfully, click "Activate Plugin". Now that the Ghost plugin is installed and activated, you're now ready to begin exporting your data from Wordpress.

Once you're on that page, you should see a button that says "Download Ghost File". If you click on that, You will be prompted to download a file. This is the file that will be used to import your posts so be sure to keep it in a safe place.
