End of Life (EOL) for Drupal: Understanding the Impact & Navigating Upgrades

Understanding EOL in Software

End of Life (EOL) in software refers to the point at which a version of a software product ceases to receive support — including technical assistance, updates, or security patches. Once a software reaches EOL, developers no longer address emerging bugs, vulnerabilities, or compatibility issues. This phase often occurs as newer versions are released or when the older version becomes obsolete in the context of current technology.

Drupal Version EOL Dates and Their Significance

Drupal, as a robust CMS and framework, experiences regular updates and improvements, with each major version having a predetermined lifecycle. Let's review the EOL dates for various major Drupal versions:

• Drupal 6: EOL reached on February 24, 2016.
• Drupal 7: Initially set for EOL in November 2021, extended to November 2022, and then to January 2025!
• Drupal 8: EOL reached in November 2021.
• Drupal 9: EOL reached in November 2023.
• Drupal 10: Released in 2022, with its EOL currently anticipated around late 2024 or early 2025.

The EOL for these versions means that the Drupal community will no longer provide official support, security updates, or bug fixes. This poses significant security risks, as websites using outdated versions become vulnerable to new threats and compliance issues.

The Flexibility of EOL Dates in Drupal

EOL dates in Drupal aren’t always fixed, as seen with Drupal 7. Reasons for extending EOL dates include:

1. Community Support: Strong demand and active community support for an older version can lead to extensions.
2. Migration Challenges: The complexity of migrating to newer versions can delay the retirement of older versions.

Navigating Major Drupal Website Upgrades

Upgrading a major version of a Drupal website involves several steps:

1. Assessment: Analyzing the current site for compatibility.
2. Backup: Securing all data and configurations.
3. Module/Theme Updates: Updating or replacing incompatible modules and themes.
4. Core Upgrade: Migrating to the new Drupal core.
5. Data Migration: Transferring content and configurations.
6. Testing: Ensuring functionality and security.
7. Deployment: Moving the updated site to production.

The Role of Professional Expertise in Upgrades

Given the complexity and potential risks of upgrading a Drupal website, it is advisable to engage experienced Drupal professionals. Their expertise is vital in ensuring a smooth transition, minimizing downtime, and addressing any challenges that arise during the upgrade process.

Upgrade Variability Across Software Systems

The ease of upgrading between major versions varies across different software systems. This variability is influenced by factors like the architecture of the software, changes in the new version, and the availability of migration tools. Some systems offer straightforward upgrades, while others require extensive modifications.

Considering Total Cost of Ownership (TCO)

When facing substantial upgrade costs, it's an opportune time to evaluate migrating to a different platform. A platform with a more manageable upgrade path can significantly reduce the TCO, ensuring a sustainable and cost-effective online presence.

At Itomic / Drupalise we specialise in both Drupal AND WordPress, with no technical or commercial bias towards either. Horses for courses! We are therefore very well positioned to evaluate whether your longer-term interests are better served by Drupal OR WordPress, or potentially other custom software like the Laravel framework.
