LinuxSecurity.com has been using the open-source Joomla Content Management System (CMS) and Hypertext Preprocessor (PHP) scripting language for nearly three decades and recently migrated to the latest versions, Joomla 4 and PHP 8. This allows LinuxSecurity to use new features and optimizations to provide visitors with an enhanced user experience. We’ve decided to pull back the curtain on our experience with the migration to Joomla 4 and PHP 8 to give users planning to migrate their websites insight into the lessons we learned.

Without being too technical, both Joomla and PHP offer improved performance, ultimately giving the LinuxSecurity user base an improved and secure experience while visiting LinuxSecurity.com”.

Our Migration Experience

Overall, our migration to Joomla 4 and PHP 8 went pretty seamlessly. This outcome can be partially attributed to our careful planning, documentation, and team meetings, which helped iron out any possible data and network security issues. Hodara reflects, “We were well prepared with the amount of research, documentation, and testing done before going live with the upgraded site.” Below, we have listed various suggestions to keep in mind if your company plans to migrate to Joomla 4 and PHP 8.

Our Top Suggestions for Users Migrating their Websites to Joomla 4 & PHP 8


Check in with your developer to ensure all areas of your Joomla site are PHP 8 compatible, from extensions to templates and plugins. We found it helpful to locate the changelog and scan the document for PHP 8 references. Joomla 3.10.10 offers a Pre-Update Check report to see if it is or is not compatible with Joomla 4. If a system is not ready for Joomla 4, you may have to consider a different extension that offers the same functionality. 


You will want to set up a staging environment to test PHP 8 and Joomla 4. The testing process can be lengthy, depending on the website's complexity. We recommend using a staging site to test your website correctly.


Document any file modifications made for future reference. More importantly, document the process to launch the site, as you may need to refresh some data or content on the staging site.

Testing & More Testing!

After you’ve completed either upgrade, be sure to test every part of the website thoroughly. You will want to do a visual and functional check (form testing, user registration, user login, etc.). All of this will be helpful in checking that your company’s data and network security are strong enough after the migration.
