When is a Suitable Time to Upgrade to New Versions of Software?
In the ever-evolving tech landscape, upgrading software is an important decision that can influence an organisation’s operational efficiency, security, and overall success. This article delves into the timing of software upgrades, using the Drupal website content management framework as a primary example to illustrate key concepts. We’ll explore versioning, software lifecycles, SaaS versus traditional software models, and more, to help business and technology leaders and managers make informed decisions about when to update their systems, and who to manage the project.
Understanding Software Versions
Software versioning is a standardised way to denote changes and improvements in software. The format X.Y.Z helps categorise these changes:
- Major Version (X): Represents significant updates, including new features or substantial changes. Upgrading to a new major version (e.g., Drupal 9 to Drupal 10) often involves comprehensive changes that may affect compatibility with existing systems and customisations. This could require significant testing and adjustment.
- Minor Version (Y): Involves enhancements and additional features that are generally backward-compatible. Upgrades to minor versions (e.g., Drupal 10.1 to Drupal 10.2) usually offer new functionalities without major disruptions.
- Patch Version (Z): Focuses on fixing bugs and vulnerabilities. These updates are typically minor and address security issues or improve performance without altering existing features.
When considering an upgrade, evaluate how each type of version change will impact your current system, including the need for reconfiguration, retesting, or potential downtime.
Software Lifecycle Stages
Software goes through several stages before reaching a stable release:
- Alpha: Early development phase, often with incomplete features and frequent bugs. Suitable mainly for developers and internal testing.
- Beta: More stable than alpha but still subject to significant changes based on user feedback. Beta versions are useful for identifying issues that may not have been caught during internal testing.
- Release Candidate (RC): Almost final version, with most major issues resolved. RC versions are close to the final release and offer a near-complete view of what the stable release will look like.
- Stable: Fully tested and considered production-ready. This version has undergone extensive testing and is suitable for most users. But it’s important to note that late adopters (see below) will typically wait at least another 6-12 months before upgrading. This is particularly true for many Drupal website owners, because even though the Drupal core is considered to be ‘stable’, it can take months before the bulk of popular Drupal modules are fully upgraded to be compatible with the new core. In this example it’s less costly to upgrade late, than it is to upgrade early.
Understanding these stages helps businesses gauge the maturity and reliability of a software version. For critical systems, waiting until a version reaches the stable phase is usually advisable to minimize risks.
SaaS vs. Traditional Software
Software as a Service (SaaS): SaaS providers typically handle all aspects of software maintenance, including upgrades. This model ensures that users always have access to the latest features and security updates without managing the upgrade process themselves. Occasionally users will be given options, or compelled, to migrate their systems from old SaaS platforms or new SaaS platforms, e.g. Google’s switch from Universal Analytics to Google Analytics 4.
Traditional Software: With traditional, on-premises software, businesses must manage their upgrades. This includes planning, testing, and executing the upgrade process, often requiring dedicated IT resources, internal or 3rd party. The responsibility for ensuring compatibility and minimizing disruption falls on the organization and their tech team.
Understanding whether your software is SaaS or traditional influences your upgrade strategy. SaaS models generally offer more convenience and reduced risk during upgrades, while traditional models offer more control but require more resources and planning.
Early Adopters vs. Late Adopters
Early Adopters: These businesses jump on new software versions as soon as they are available. They benefit from new features and innovations ahead of competitors but face potential risks such as untested bugs and compatibility issues. Early adoption is often suitable for tech-forward companies or those with robust IT support who can handle potential disruptions.
Late Adopters: Waiting until a new version has been thoroughly tested and refined offers stability and minimizes the risk of encountering critical issues. This approach is often preferred by organizations with limited IT resources or those relying on mission-critical systems where stability is paramount.
Balancing the benefits of new features with the risks of potential issues is key to determining the right adoption strategy. Each organization’s needs and risk tolerance will dictate the best approach.
End-of-Life (EOL) Considerations
End-of-Life (EOL): When software reaches EOL, it no longer receives updates, including security patches. Continuing to use EOL software exposes your organization to increased security risks, compliance issues, and potential incompatibilities with newer technologies.
- Increased Risks: As vulnerabilities are discovered, they remain unpatched, making the software a target for attacks.
- Compatibility Issues: Newer integrations and technologies may not work with EOL software, causing operational challenges.
- Cost Implications: Maintaining outdated systems often requires more effort and resources, potentially leading to higher costs over time.
While using EOL software does not immediately cause operational collapse, the long-term risks and costs can outweigh the benefits of delaying an upgrade.
Open Source vs. Proprietary Software
Open Source Software: Often encourages community participation, leading to rapid feedback and iterative improvements. Open source projects like Drupal benefit from extensive community testing and contributions, which can accelerate the refinement of new versions. However, the quality of these versions can vary, and businesses may need to rely on community support.
Proprietary Software: Typically follows a more controlled release cycle, with thorough internal testing by the vendor. While updates might be less frequent, proprietary software usually offers well-supported and stable releases. Vendors handle bug fixes and updates, but this model may not benefit from the broad community insights available to open source projects.
Understanding the differences between open source and proprietary models helps in assessing the level of support and stability you can expect from each software upgrade.
Deciding Between Internal and External Resources for Major Version Upgrades
When it comes to major version upgrades, the stakes are higher due to the substantial changes and potential risks involved. This decision often requires careful consideration of whether to rely on internal resources, external consultants, or a combination of both. Here’s a detailed look at the factors influencing this decision and how to choose the right approach for your organization.
Internal Resources
Advantages:
- In-Depth Knowledge: Internal teams already understand your organization’s systems, customizations, and business processes. This familiarity can lead to smoother transitions and fewer surprises.
- Alignment with Business Goals: In-house staff are often more attuned to your organization’s strategic objectives and can ensure that the upgrade aligns with these goals.
- Cost Control: Using internal resources can be more cost-effective in terms of direct expenses, avoiding the high fees associated with external consultants.
Disadvantages:
- Limited Expertise: Your internal team might lack specific experience with the new version of the software, especially if it’s a major update involving complex changes.
- Resource Constraints: Existing workloads and responsibilities might limit the availability of your team for a major upgrade project.
- Training Needs: Significant training may be required to bring internal staff up to speed with new features and functionalities, potentially delaying the upgrade process.
Best for:
- Organizations with a highly skilled internal IT team familiar with the software and its intricacies.
- Businesses looking to minimize costs and maintain control over the upgrade process.
External Resources
Advantages:
- Specialized Expertise: External consultants or firms often bring extensive experience and specialized knowledge of the software version. They can provide insights into best practices and avoid common pitfalls.
- Faster Implementation: Experienced external resources can expedite the upgrade process due to their familiarity with similar projects and their focus on the task.

Disadvantages:
- Higher Costs: Engaging external consultants can be expensive, especially for complex upgrades requiring extensive involvement.
- Less Organizational Knowledge: External resources may need time to understand your specific configurations and business processes, potentially leading to longer onboarding times.
- Limited Control: Relying on external resources means relinquishing some degree of control over the upgrade process and its outcomes.
Best for:
- Organizations lacking in-house expertise or resources to manage a major upgrade effectively.
- Businesses that need to implement the upgrade quickly and efficiently, leveraging external specialists’ experience.
Hybrid Approach: Combining Internal and External Resources
A hybrid approach can often provide the best of both worlds by leveraging the strengths of both internal and external resources:
Advantages:
- Balanced Expertise: Internal teams can handle familiar aspects of the upgrade while external consultants address specialized or complex components.
- Shared Responsibility: External experts can guide the process and provide training, while internal staff manage day-to-day operations and integration.
- Cost Efficiency: Using external resources for specific tasks or phases can be more cost-effective than outsourcing the entire upgrade.
Best for:
- Organizations that want to maintain control over the process while benefiting from specialized external expertise.
- Projects that require both deep internal knowledge and specialized external skills to succeed.
Choosing the Right Approach
To determine whether to use internal or external resources—or a combination of both—consider the following factors:
- Scope of the Upgrade: Assess the complexity of the upgrade and the specific skills required. Major version upgrades often involve more significant changes, which might necessitate external expertise.
- Internal Team Capabilities: Evaluate the skills, experience, and availability of your internal IT staff. If they have the necessary expertise and time, they may be able to handle the upgrade with or without external assistance.
- Budget Constraints: Determine the budget available for the upgrade. If cost is a major concern, a hybrid approach may offer a balance between cost and expertise.
- Timeline Requirements: Consider how quickly the upgrade needs to be completed. External resources may accelerate the process, while internal teams may need more time due to existing responsibilities.
- Risk Management: Weigh the risks associated with the upgrade. External consultants can help mitigate risks with their experience and specialized knowledge, but internal teams can provide more detailed insights into your specific system and needs.
By carefully evaluating these factors, you can make an informed decision about whether to manage a major version upgrade with internal resources, external consultants, or a combination of both. This strategic approach will help ensure a smoother transition and successful implementation of the new software version.
Conclusion
Determining the right time to upgrade software involves evaluating multiple factors, including:
- Impact of Version Changes: Assess how major, minor, and patch updates will affect your current system.
- Lifecycle Stages: Understand the software’s maturity and stability at different stages.
- SaaS vs. Traditional Models: Consider whether your software provider handles upgrades or if you need to manage them yourself.
