There are two options. The first is to perform the export yourself at no cost.

Sign into your Wordpress Site
  • Navigate to Tools > Export
  • Choose what to export and click Download Export File
  • This will provide you with an XML file that can then be uploaded into a fresh Wordpress installation

The second option is to have Blackbaud perform this export for you.
 
  • Contact Support and ask them for a copy of your site's data.
  • They will forward this request to our internal teams.
  • They will provide you with an XML file that can then be uploaded into a fresh Wordpress installation
  • They will also provide a copy of your site's media files


Please note that neither of these options will include plugins. To obtain these, you'll need to download them from https://wordpress.org/plugins/ or purchase them yourself. Blackbaud will not provide any plugins that were created in-house.
