Hello @Bekahpogue,
Thanks for writing to us.
In case if you have not used builder in the post to edit the post in that case you can export the only post by using the default WordPress feature. Please have a look at the given screenshot below.
Tool—>Export–>Post–>Download Export File
Now go to another site where import–>Tools -->Import—>It would require WordPress Importer Plugin
Please note that it would only work properly if your WordPress installation is blank since it might conflict with post ID and Media Attachment ID if you have created a post on your page and uploaded an image there in the site where you want to import.
In case if you want to migrate the full site please have look at our migration doc.
Hope it helps
Thanks
