What Migrate K2 Pro can do for you
Turn K2 items into core Joomla articles
Each K2 item becomes a core Joomla article with its title, alias, intro and full text, category, published state, featured flag, access, language and ordering.
Created, modified and publish dates, hits, meta description and meta keywords carry over. Articles keep the same Joomla user as the author, and you can set a fallback user for items with no author.
Keep your category tree and tags
K2 categories become Joomla categories with the same parent-child hierarchy, title, alias, description, published state, access and language.
Published K2 tags become Joomla tags, and each article keeps its tag links.
Bring extra fields into Joomla custom fields
Published K2 extra fields and field groups become Joomla custom fields, with their types, labels and each article's values. Unusual K2 field types become text fields.
List, radio and checkbox options are carried across for you to review in Joomla's field manager.
Copy your main images and fix their paths
The single K2 main image for each item is copied to a Joomla folder you choose and set as both the article's intro and full image. Its caption becomes the alt text and caption, and image credits are added to the full-image caption.
media/k2/ paths in article text and field values are rewritten to the new folder. Images are copied, so the originals stay in place.
Redirect old non-SEF K2 item URLs
Migrate K2 Pro can create 301 redirects from old non-SEF K2 item URLs (index.php?option=com_k2…) to the new articles.
The redirects work through Joomla's Redirect plugin, and you can add any SEF URLs in Joomla's Redirects manager.
Export your K2 data as CSV, JSON or SQL
Download K2 items, categories, tags, extra fields, comments and attachments as CSV, JSON or SQL, one table at a time or all at once.
Export comments and attachments to CSV, JSON or SQL too, with or without running a migration.
Run it safely, and roll back if you need to
Pre-flight checks confirm that K2 is present, check the media and image folders, and flag category alias conflicts. Items then move in batches with a live progress bar, automatic retries and a Retry button, and a re-run picks up only new content.
Your K2 tables stay untouched. Every run is recorded in the migration log, and Reset cleanly removes what the migration created and reports what it removed.
Compatibility
Native Joomla 3 component. Migrate on Joomla 3 first, then upgrade your site.

How do I get from K2 on Joomla 3 to a newer Joomla?
Install Migrate K2 Pro on your Joomla 3 site and migrate your K2 content to core articles. Then remove K2 and any extensions that depend on it, and upgrade Joomla through its standard upgrade path.

Yes. A re-run picks up new K2 content and leaves what's already migrated in place. You can also roll back and start again.
