Joomla Maintenance: Keeping Your CMS Secure and High-Performing

Joomla differs from other CMS platforms through its architecture: the framework-based system with MVC concepts, the component-module-plugin triad and the standalone template system offer great design freedom but also create complex dependencies. A typical Joomla installation uses ten to thirty extensions, often from different developers with different release cycles and support lifespans. When the Joomla core moves to a new version, every extension must be checked for compatibility — an effort that quickly turns into a backlog without structured maintenance processes.

Particularly relevant is the generational shift from Joomla 3 to Joomla 4 and Joomla 5: Joomla 3 has not received security updates since the end of 2023 (Joomla Security Team). Websites still running on Joomla 3 face increasing exposure without active security care. Migration is not a simple update click: the new Bootstrap-5-based framework, the revised ACL system and the new media manager architecture require a thorough audit of all extensions and custom modifications before the migration to the staging environment begins.

For many Joomla operators, migrating from Joomla 3 to a current version is the most urgent task in the coming months. Joomla 3 has not received security updates since the end of 2023. Operating without active patches is irresponsible toward visitors whose data is processed on the website, and conflicts with the GDPR obligation for technical security. At the same time, migration is not a routine update: the internal architecture of Joomla 4 differs fundamentally from Joomla 3. The new template system (Cassiopeia instead of Protostar), the revised database layer and the updated extension API mean that old extensions, templates and custom modifications must be checked for compatibility and replaced where necessary before migration.

We carry out Joomla migrations as structured projects: first, a full inventory of all extensions with an assessment of their compatibility with Joomla 4/5 and PHP 8.x. Then setting up an identical staging environment where all migration steps are rehearsed. Extension upgrades and template adjustments in the controlled environment, intensive functional testing of all page sections and forms. Finally, the live migration during a defined maintenance window with a prepared rollback plan. This approach minimizes risk and ensures your website runs on a current foundation after migration.

If your Joomla website is already compromised, every hour counts. We clean infected installations, close the point of entry and document the measures — the website cleanup starts at a fixed price from €390 (net) after a free initial check. For acute problems outside a maintenance contract — website unreachable, extension conflict or errors after an update — we provide immediate help at €95 per hour (net, billed in 15-minute increments). You will find the details and the direct hotline on our emergency support page; after the cleanup, we secure your Joomla site for the long term with an ongoing maintenance contract.

For Joomla installations, we set up a multi-tier backup strategy that accounts for the specific characteristics of the CMS: alongside the filesystem and database, Joomla also requires consistent backups of the configuration file configuration.php, the media manager content and extension-specific configurations. Daily full backups are created automatically and stored in a geographically separate data center in Germany. Retention periods follow your operational requirements — by default we keep the last 30 daily, seven weekly and three monthly snapshots. Monthly restore tests in an isolated environment document the recovery time — so we know exactly how long it takes to bring your Joomla website back online in an emergency. The backup service is integrated into all of our maintenance packages.
