K2 to Content Migration

K2 is a popular extension of Joomla. It always tops the list of most loved apps on versions J1.5, 2.5 and 3.

However, they still don't have a roadmap for Joomla 4 which is why you have to go back to Joomla Content, the default built-in extension on Joomla.

This tool makes it possible for you to migrate K2 articles to Joomla Content. Thereby, you can upgrade your website to Joomla 4.

Buy Now ( $15 ) Demo

It is designed for ease of use. Note because K2 is not available on Joomla 4, so you only use this tool for Joomla 3.

Imported data includes:

  • All K2 Articles + Intro Image
  • All K2 Categories
  • All K2 tags
  • All K2 Extra Fields
  • Attachments (Required plugin installation: File Attachments)

After installing this tool, go to Components > K2 to Content to get started.

K2 to Content UI

Here, the tool will tell you what it will do. Include the number of articles and the number of categories to be imported. Click the "Import Now" button to launch.

Wait for the tool to notify you that the import is finished.

    Hi there - I am trying this out, and most of my items are failing with the error message:

    Unknown column 'Array' in 'field list'

    How can I fix this please?

      @David To follow up: I have found two places where this extension is failing for me:

      (i) K2 extra field "link"
      This data is saved as an array, and I believe this is what is giving the error message "Unknown column 'Array' in 'field list'". None of the data in the "link" extra field is migrating for me.

      (ii) K2 tags that do not appear in items
      My site contains some terms in the K2 tags list that do not appear in any K2 items. As soon as the migration comes across one of these, it stumbles, and ceases importing tags.

      Any help you can offer would be greatly appreciated. I am on a tight deadline needing to finish my migration this weekend. I sent you an email with my site details, but if you need any further information, please let me know.

    I recently purchased your "K2 to Content Migration" module. Unfortunately, all categories with an indication of the number of linked articles are transferred, but not the articles with the indication "404 Component not found". I'm a beginner, can you help me, thanks

    After the migration, the images are not displayed in the Images tab of the article. This is necessary in order to use my own templates and design articles. The links would have to be inserted in the intro and full image of the article table. Can you help me with this?

    Hi, In case of failure, is it possible to know which contents were not imported? When there are hundreds or thousands of contents, it is difficult to check manually. Having a list would be very helpful.

    I recently purchased your K2 to Content Migration tool and installed it and ran it. it successfully created all of the categories and articles but the extra fields are not being copied over correctly.

    I have configured lots of extra fields which contain very important content. It looks like it is only copy over the first field of every group?

      @JC The content of the fields is in a separate table, it is not related to the article content. If it's "Textarea", I'm not sure why it's not working properly on your website.
      Please send website information and admin account to email: contact@joomhelper.com, I will check soon.

      @David Apologies ... so the textfields ARE copied over but NOT textareas! Most of my content is in textareas.

      You should probably declare this somewhere as I feel like ive been misled somewhat.

      @David But it seems to have copied over some textareas? But not others?

      How do I give you access to the site to take a look?

      @David Fields that are not in this list are still added to the database, but Joomla content will not display it (because it is not supported).
      Note: This extension only has data migration function.

      @JC As you said, all custom fields are "textareas" type, so they will be imported to content. I'm not sure why it not work correct on your site so give me your site access, I will check it soon.

    Hi!
    I just used this tool and I have a few issues:
    1. Out of 2000 K2 items imported successfully, 700 failed. What could be the reason? The categories are by year (2008-2023) and the correct number of articles filled the categories till 2017 where only a part of them passed, and from 2018 all categories are empty. Is there a limitation?
    2. If I look at the article list and filter by category - nothing happens. If I'm trying to see, for example, the 2023 category articles (which is empty) I still see all articles.
    Can you please assist?

    Hi, after importing with version 1.1.7 my articles' IDs got inverted (older ones got higher IDs, newer ones lower IDs, e.g. last article got ID 1). Is it possible to have the newer ones with higher IDs? (Ideal solution would be the same IDs as in K2, but don't know if it's possible).
    Thanks and regards,
