Opting for proven legacy software seems to be the safest path. With business changes happening fast, IT leaders need smart strategies to keep their systems up and running.
This blog post provides practical advice on managing your legacy effectively with minimum security risks and operational overhead.
Why legacy systems persist
Staying on top of evolving technology is vital for business growth, but the pressure to adapt can be overwhelming. What if your business is not ready for change? The fear often comes from facing technical challenges and feeling unprepared. Recent research shows that a significant 36% of tech leaders see their culture as risk-averse, meaning they are hesitant to make quick changes. Common hurdles also include lacking the specific skills to drive transformation and coordinate communication, making it harder to reach the necessary maturity levels.
Let's delve into the detailed breakdown of why companies stick to the tried-and-true:
Your legacy, your asset
With a proven track record, your legacy software becomes a reliable system that has been tested and trusted over the years. This feels like a secure choice, especially for critical tasks.
Financial risks
Organizations have invested heavily in legacy systems, including the initial purchase, customization, staff training, and maintenance. Transitioning to a new system introduces new costs, acting as a potential obstacle.
Specialized functionality
The distinctive functionality is the backbone of your legacy system apart, tailored to a specific industry. In certain cases, modern alternatives cannot replicate this level of specialization, so legacy systems continue to be essential.
Regulatory compliance
In industries like finance, healthcare, or government, where stringent regulations apply, legacy software becomes a cornerstone for compliance with specific standards, making replacement challenging.
Lack of tech skills for modernization
Companies proficient in running their legacy systems may lack the necessary expertise to operate newer technologies. In such cases, sticking with familiar solutions is a pragmatic choice.
Many businesses do not necessarily jump into modernization when new technologies emerge, as it does not always match the current goals and end-user needs. However, there comes a time when action becomes paramount, as sticking with outdated legacy systems poses risks with minimal profit. So, take a step back, reassess, and consider the way forward.
When is it time to take action?
Here are clear indicators that your system may be falling short:
Outdated functionality
The system's outdated functionality makes customization, scaling, and optimization challenging, posing risks to business competitiveness and customer satisfaction.
Obsolete tech stack
An outdated tech stack hinders legacy system integration with modern tools and platforms, causing missed opportunities for innovation.
Security vulnerabilities
Exposure to security vulnerabilities compromises sensitive data, risking user privacy and undermining data integrity.
Escalating maintenance costs
Expenses, even for minor code changes, are skyrocketing, straining the budget and creating inefficiencies.
Rigid interface and features
The system's inflexible interface and features fail to captivate customers, leading to higher churn rates and impeding competitive advantage.
Accumulating technical debt
Unaddressed issues that stick around for years slow down system performance and cause future development challenges.
Recognizing these signs is critical. It's time to take proactive measures, address immediate concerns, and enable efficient operations.
4 practical steps to maintain your legacy system
With a clear strategy, businesses are well-informed to act proactively and empowered to deal with emergencies.
Assess the risks and identify benefits
Start by evaluating your legacy system and its impact on your IT environment and business objectives. Identify potential risks, weaknesses, and concerns, while also highlighting the advantages and features they bring. This assessment will help you prioritize which systems need more attention, which can be managed, and which may be phased out.
Perform patch management
Ensure the legacy system is performant, secure, and compatible. To securely apply fixes without causing issues or conflicts with other systems, set up a patch management policy and process. Use specialized tooling, monitor and test patches before deployment, and document and back up your old systems.
Keep your legacy systems isolated
Isolation involves keeping a system apart from others or your network that does not need to communicate with it. Safeguarding entails implementing security measures to prevent malicious attacks or data breaches, including firewalls, antivirus software, encryption, authentication, and VPNs. Doing so can reduce the attack surface, limit exposure, and minimize the potential risk of incidents.
Modernize or migrate
Upgrading legacy systems for improved performance, functionality, or compatibility is a key aspect of modernization. Migration involves moving legacy systems to environments like the cloud, virtualization, or containerization. Both approaches bring advantages such as heightened efficiency, scalability, and reliability, while also reducing costs, risks, and complexity. Furthermore, they contribute to enhanced security, compliance, innovation, customer satisfaction, and a strengthened competitive advantage.
