K2 is a Joomla component that enhances the Joomla features. It replaces the management of articles with the K2 items. The categories can have many levels (like Joomla 2.5 and WordPress). The items can be tagged, have a featured image, attachments and custom fields (like in WordPress). A comment system is also included (in WordPress too).
The add-on migrates all these K2 contents:
It can migrate the extra fields either to regular WordPress custom fields or to ACF fields or to Toolset Types fields. In both latest cases, you need the Advanced Custom Fields plugin or the Toolset Types plugin.
For a SEO purpose, it also redirects the URLs of the K2 items to the corresponding WordPress posts.
The add-on requires the main plugin FG Joomla to WordPress Premium.
