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 ( $19 ) Demo

* To move large number of articles (>7000) , please use Pro version:  Buy Now ( $25 )

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.

    Can this tool help me smoothly transfer them to Joomla 4?

      @Angus Chen Please use Pro version to migrate large number of articles. If you have any problem during the migration, please contact me. I will help you as soon as possible.
      This extension only migrates articles from K2 to Joomla Content, the URL may not be the same, it depends on your site configuration.

    Hi. Great job. It works for me in seconds, but it doesn't move the images out of K2. Do images need to be moved to another folder? Need help with this. Thank you.

      @Gustavo Morales Hi!
      Maybe I'm not understanding what you mean. Do you mean that the intro images of the featured items are not moved to the new folder? By default, all intro images will be imported to folder images/k2.

      @David Got it. Thanks. Anything else I can do with importing the images? It only imports the images directly embedded in the posts, but not the featured k2 image.

      @Gustavo Morales Hi!
      The images in the article will still be stored in the k2 media folder. I recommend you keep this folder.

    I have migrated the K2 content over to Joomla content with no problems, but the K2 Extra Fields aren't being migrated over and any K2 Items which had extra field values set aren't being migrated as Joomla Custom fields. Have I done something wrong please?

    Hi,
    I've just installed the component to migrate K2 to articles on a very large site, and I have some problems:

    I have 5000+ tags, and only 1400 were moved to Joomla tags.
    What is the best practice for migrating the K2 items and saving the same IDs that I was using in the K2 items and categories if I already have articles and categories with the same IDs? Do I need to delete them before and check the box to "use the same K2 ID"?
    The custom field type "select" doesn't seem to migrate correctly to Joomla fields. It adds the field but not with the correct type, and it fails to move the corresponding data to it.

    Please let me know if you have any suggestions or solutions to these issues.
    Thank you,

    Thank you for the extension. I'm able to convert a portion of my k2 items and categories.

    The log file shows a few messages like this:
    - Item: 台北凱撒大飯店 Caesar Park Hotel Taipei:Duplicate entry '1-1163-53' for key 'uc_ItemnameTagid'

    - Item: Mega 50餐飲及宴會．望月樓:Duplicate entry '1-1164-53' for key 'uc_ItemnameTagid'

    - Item: 湄公河南洋美食:Duplicate entry '1-1168-53' for key 'uc_ItemnameTagid'

    - Item: 鄉園本港海鮮餐廳:Duplicate entry '1-1169-53' for key 'uc_ItemnameTagid'

    - Item: Mega 50餐飲及宴會．望月樓:Duplicate entry '1-1172-53' for key 'uc_ItemnameTagid'

    - Item: 台北凱達大飯店 Caesar Metro Taipei:Duplicate entry '1-1173-53' for key 'uc_ItemnameTagid'

    - Item: Mega 50餐飲及宴會．望月樓:Duplicate entry '1-1176-53' for key 'uc_ItemnameTagid'

    What would you suggest me to do to get this duplicate entry issue fixed?

    Thank you.

    This is not importing all identified articles. It says 4175 identified, but only imports about 1290, then just gets stuck.

      @Sean Kalinich In some cases, the process is stopped due to the Timeout parameter set on the server.

      Could you send me your site access to my email? (contact@joomhelper.com). Please help me back up your website first.

    K2 to Content Migration Version 1.3.7, Joomla 3.10.12, PHP Version 8.1.27
    When run, after just a second or two *K2 to Content Migration* shows:
    It is estimated that **82** articles and **8** categories will be imported into Joomla Content.
    I set *Process K2 Intro Image* to *Both*
    Upon **Import Now**, I see: success: 25, failure: 0
    --- LOG FILE ---

    There is no further indications on the K2 to Content Migration Administration page even if I let it 'run' for 30 minutes.
    Number of K2 Items: 82, Number of K2 categories: 9
    Number of original articles: 15, Number of original categories: 1
    Number of articles after attempted migration: 65, Number of categories after attempted migration: 17
    I ran the extension twice. Apparently the converted articles and categories were duplicated. The log file only has this content: --- LOG FILE ---
    There was no success message or any indication that the process was finished. It dies silently. Can this extension be repaired?

      @David There should be a log file that is available to see what the error is.
      If there is a log file, where is its located?

    Hi David, I have one doubt that concerns the urls of k2 articles. I do not use any third party components. Would they remain the same?

      David · 8 months ago
      @Boskizzi I'm not sure about this because it depends on the URL structure of each element. If the structure is the same, the link will be preserved.

    I currently have about 179 existing joomla articles, and some of the k2 items that will be migrated have the same ID.

    Based on that, what would you recommend for the "Keep k2 ID" option?
    Thanks!

    Hi David, Just downloaded and converted 3200 K2 items to articles. Looks like it worked perfectly. A couple of questions. I could not find these answers in searching past comments, so sorry if they are redundant:

    1. Since the articles now have the same "alias" as the K2 items did, and it seems to be calling up the article (correctly) when entering the SEF URL, what happens/ed to the K2 items' aliases? Is there going to be a conflict at some point?

    2. Although they are converted, for some reason the tags are not working properly (i.e. "clicking" the tag doesn't list the articles with that tag).
    Thank you. This was quick and painless.

      @David David,

      Converted the k2 items and categories perfectly. It's a great product and worked flawlessly, except for one thing:

      For some reason, it didn't convert the tags.

      I haven't made changes to any articles since converting/migrating, and I have a copy/staging site in which all the tags are available. It also looks like the content/article ID numbers line up.

      Question: Is it feasible/possible to "drop" the existing content tag table (contentitem_tag_map) and import the tag table from the copy/staging site? If so, are there other tables that should be included?

      Please advise.

      Thank you!

      @David It's seems to be working fine when entering the URL of the article into the browser. I know I need to tweak the menus and modules, etc. I guess I"m all set.

      As for the question about the "tags," I believe it's acting up because I had the joomla tags turned off while using K2. I'm sure correcting that will resolve it. If not, I'll reach out.

      Thanks for a great product! It worked very well. I appreciate it.

      @Gerald Neale Hi,
      1.The SEF URL will include the menu alias. So if you set Menu to content or k2, it will not conflict.
      2.I remember I fixed this. Could you send your site access to my email contact@joomhelper.com ?

    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?

      Zellie · 9 months ago
      @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.

    are all converted to Joomla custom fields with your plugin?

    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?
