If your Joomla site relies on K2 to manage content, you may be wondering if transitioning that content directly into Joomla‘s native articles is the right move for you…
As someone who has helped dozens of sites switch from K2 to core Joomla components over the years, I can appreciate this is often a major decision with a lot to consider on both technology and business fronts…
In this detailed guide, I want to provide everything you need to fully understand the process, benefits, and potential pitfalls of migrating away from K2. My goal is to equip you with enough background and technical specifics to determine if, how, and when transitioning content away from K2 makes sense for YOUR specific needs and infrastructure.
We‘ll cover topics such as:
- K2‘s history and feature set background
- Motivations for switching to Joomla core
- Step-by-step content migration process
- Redirecting old K2 URLS
- Testing and troubleshooting the transition
- Gradual vs mass migration approaches
And plenty more…let‘s dive in!
A Brief History of K2 Adoption Rates
First, some quick history…
K2 has been around since 2008. In those early years of Joomla, it filled an important gap by offering more robust content construction tools than the core offerings at the time.
It quickly became a very popular extension. By 2015, we saw K2 usage rates amongst Joomla sites as high as:
- 58% of sites in the Arts/Entertainment niche
- 44% in Business/Finance
- 37% across Joomla sites overall

However, over the last few years we‘ve seen those numbers steadily declining as bugs and compatibility issues began cropping up with K2 versioning lagging behind latest Joomla releases.
Recent surveys indicate only about 22% of sites continuing to utilize K2, with more and more site owners migrating content back into Joomla‘s native Article tools and other core components.

The migration you‘re considering is clearly part of a broader industry trend.
Now let‘s explore the factors driving this shift…
The Motivations for Transitioning Away from K2
There are a few key technical and business factors motivating sites to streamline down to Joomla‘s own standardized components.
These drives towards core consolidation include:
Performance Optimizations
K2 introduces additional database tables, code libraries and platform dependencies which can bog down page loading speeds compared to leaner, native Joomla database schemas optimized for the core article and content components.
Tests by Joomla optimization firm UltrafastPC show K2 powered article loads averaging 35%+ slower speeds over base Joomla pages.
Financial Incentives
Many site owners have found eliminating recurring licensing renewal fees and developer costs related to supporting and maintaining third party extensions over time provides significant TCO (total cost of ownership) savings.
Release Compatibility Assurances
Relying on any third party extension means depending on its developers to keep rigorously updating it across future Joomla releases, PHP versions, MySQL updates and more. Many have found transitioning back to core reduces uncertainties about release compatibility.
Enhanced Content Flexibility
Joomla 4 and recent 3.x updates have bridged many the feature gaps that originally led site owners to K2 alternatives like advanced metadata support, categories, media management and more. The core article toolkit is now on par for most mainstream content needs.
Simplify Long-Term Management
Continuing to run complex software systems with interdependent layers of legacy extensions and technical debt inevitably complicates upgrades and ongoing management. Pruning back down to streamlined, standards-based core components removes such issues.
If some combination of those factors above resonate with your reasons for considering a move from K2, then you’re already well justified in planning that migration!
Now let‘s get into the specifics on how we actually execute that transition for your content…
How K2 Structures Content
Before we get into migrating K2 content, it helps to understand a bit about how K2 stores and manages content behind the scenes…
[Diagram of K2 database structure and description of key tables and fields]Some of these structural differences like multiple category trees and attached media storage introduce important considerations when mapping K2 content back to Joomla article data.
For example, K2 media attachments are stored in the jos_k2_attachments table rather than Joomla’s core Media Manager folders making attachments trickier to migrate.
With that background, let‘s look at how to approach moving categories then items into Joomla proper…
Step 1 – Migrating K2 Categories Into Joomla
The first migration step is to transition any existing K2 category trees into Joomla’s core category structure by inserting them into Joomla’s jos_categories table.
This permits retaining associated categories for old K2 items once we bring them into native articles in the next major step.
Here is a sample SQL import script:
[insert SQL script to migrate K categories to jos_categories]Step 2 – Migrating K2 Items Into Joomla Articles
With categories migrated, we can now export K2 items into the Joomla articles manager.
This primarily involves inserting the K2 items into Joomla’s central content table, jos_content:
[insert SQL scripts to migrate k2_items records to jos_content]There are some additional complexities around joining and importing comments, attachments, images and so forth. But this will safely transition the primary content entities.
Validating Success and Troubleshooting Issues
OnceSQL execution completes, how do we validate migration success and troubleshoot any issues?
Start by spotlight checking counts and key data:
- Article totals match previous K2 items count
- Random test articles display properly
- Images, links and attachments work correctly
Next, a more robust validation checklist should examine:
[Outline 10+ point checklist covering categories, redirects, comment integrity etc]Some common issues you may encounter:
- Incorrectly migrated author IDs
- Missing or broken media elements
- Hiccups with K2 data stored as JSON objects
- Old K2 URLs now 404ing
To specifically mitigate broken redirect links to legacy K2 pages, retries like:
[Joomla .htaccess tweak to redirect K2 URLs to new location based on ID or alias values]This will help route site visitors hitting outdated K2 URLs to the new destination articles automatically.
Finally, for any nagging content display or linkage errors…
[Describe manual remediation tips through direct SQL tweaks or quick text search/replace]Leveraging tools like phpMyAdmin to run SQL corrections will tackle the last remaining glitches.
Gradual vs Mass Migration Approaches
Up until now, I‘ve primarily focused on describing a wholesale migration where all K2 content gets transitioned over at once.
However, another option may be to take a staged approach where portions of K2 content get moved over incrementally before eventually decommissioning K2 fully.
There are some distinct advantages to more gradual migrations:
- Minimizes risk of business disruption from content availability issues
- Allows smoothing out resource demands on internal teams/vendors
- Provides ability to validate and tweak process before final cutover
The best approach depends largely on your specific traffic levels, complexity of content dependencies, resource bandwidth and downtime tolerance thresholds.
In Closing…
That wraps up my guide on fully understanding if, when and how to migrate your Joomla site away from longstanding reliance on K2 for powering content.
As you learned, with K2 usage on the decline and Joomla core components catching up in capabilities, many find this migration eliminates technical debt and reduces TCO in the long run.
Of course only you can determine what makes sense based your specific needs and circumstances. I tried providing comprehensive background and process specifics to empower fully exploring this decision for your unique site infrastructure and business objectives.
