Many business owners choose outdated software due to cost worries about updating legacy systems. Although this may seem reasonable initially, depending on legacy applications will likely cause vital problems in the future.
A significant number of business proprietors opt for outdated software driven by concerns over expenses linked to modernizing legacy systems. While this approach might appear rational at first glance, relying on legacy applications is poised to trigger critical complications down the line. Stay tuned for insights on this crucial topic!
What does Legacy Modernization Mean?
Businesses often continue using legacy systems to support essential processes, even though these systems have become obsolete. For instance, they utilize outdated ERP (Enterprise Resource Planning) systems, EHR (Electronic Health Records) systems, LMS (Learning Management Systems), CRM (Customer Relationship Management) programs, databases, and other applications. Businesses delay necessary migrations of these applications for years due to perceived complexities and risks, allowing them to remain functional. For instance, these migrations could require substantial data transfer and user retraining. A typical worry involves possible downtime. Yet, by planning well and employing modern migration tools, these concerns can be eliminated. Regarding the modernization of legacy applications, the choices are "lift-and-shift" and "refactoring". To minimize disruptions, organizations can carry out application refactoring step-by-step post "lift-and-shift" cloud migration. All these approaches have pros, cons, costs, risks, and timeframes. Rehosting, or lift-and-shift migration, is the easiest: it moves on-premise apps to the cloud without changing the code but offers fewer opportunities. In contrast, refactoring takes more time and resources by rethinking business logic and redesigning software, leading to better performance. That embodies the risk-return principle, balancing minimal effort and risks with increased value and outcomes.
Legacy Software Risks
According to Gartner Inc., 91% of CIOs said that technical debt caused by legacy software hampers agility and delivery speed.
Upgrading legacy software enables companies to stay current with tech trends, tackle industry challenges more efficiently, and offer improved user experiences to clients. Here are additional reasons for businesses to opt for application upgrades:
- Legacy applications struggle to scale for expanded functionality.
- They lack compatibility with contemporary tools and applications.
- Mobile support is frequently absent.
- They operate on outdated design patterns, resulting in subpar performance.
- Moreover, their obsolete design exposes them to escalating security risks.
Legacy Application Modernization Challenges
Regrettably, BCG's report indicates that only 30% of modernization projects have achieved their objectives, casting doubt on businesses. However, should this genuinely deter you from advancing your modernization strategy? In reality, many organizations contend with fixable problems. How to manage them? Begin by identifying them ahead of time.
- Poorly designed, developed, or documented legacy systems can bring about substantial hurdles during redesign and transition.
- A lack of a clear strategy and execution plan might result in setbacks and unexpected complications during migration.
- Insufficiently assessed migration of legacy apps and dependencies can trigger system failures.
- Issues like network downtime and data access during migration can severely disrupt business productivity.
- Prioritizing platform transition over user experience can lead to negative customer feedback and client loss.
- Legacy system upgrades often take time, potentially surpassing budgets and forcing companies to stick with current systems.
How to Overcome Obstacles?
If your outdated software malfunctions, the sole solution is to modernize it. The challenge arises because as a business owner, especially without technical know-how, you might feel uncertain about the process of upgrading legacy applications:
- Who designs the modernization plan?
- Who executes this plan?
- How do you find experienced staff or choose an external partner?
- What's the potential cost of updating legacy software?
- Which pricing model to choose if you rely on a contractor?
Conducting both business and technical audits helps uncover the optimal middle ground in your cloud migration strategy.
From a business standpoint, three crucial considerations are:
- Does the legacy application meet the demands of digital businesses?
- Is upgrading our old software to boost our business value necessary?
- Do our legacy systems align with agility principles?
From an IT perspective, these three drivers are essential:
- What are the risks associated with using outdated IT components?
- Is the overall maintenance cost of legacy systems reasonable?
- Is the technological complexity manageable?
When several drivers align from both business and technical perspectives, new opportunities arise, and strategies to capitalize on them become evident.
Why Migrating to the Cloud is One of the Best Options
One highly effective method for migrating legacy applications involves shifting them to the cloud. Now, let's examine the benefits of adopting the cloud compared to maintaining legacy applications.
Reduced costs. Cloud services enable businesses to pay solely for their usage and scale resources as needed. Simultaneously, cloud providers manage maintenance and software updates and offer a range of services without extra charges
Improved access and mobility. Cloud-based applications ensure strong availability and back modern user devices. That enables round-the-clock access from anywhere and facilitates simultaneous collaboration by multiple users on the data.
Accelerated scalability. Businesses can adjust app sizes for storage and introduce cloud services to boost features and performance monitoring. Integration with cloud-hosted SaaS apps is also feasible.
Enhanced data security. Cloud systems stay updated for security compliance and provide inherent security mechanisms like permission-based rules, policies, security analytics, and enterprise visibility tools.
To Conclude
Navigating the complexities of legacy application modernization requires addressing both business and technical challenges. Despite initial cost concerns, relying on outdated software can lead to significant future issues.
Legacy systems, while obsolete, often support critical processes, leading to delayed migrations. By carefully planning and using modern migration tools, concerns like data transfer and downtime can be minimized.
Overcoming obstacles involves clarifying responsibilities, identifying expertise, and understanding costs. Conducting business and technical audits helps uncover an optimal cloud migration strategy, aligning drivers from both perspectives to seize new opportunities.
Migrating to the cloud emerges as a powerful option for legacy modernization, offering reduced costs, enhanced access and mobility, scalability, and advanced data security. The companies that opt for transitioning their legacy systems to the cloud can benefit from these advantages ensuring a more agile and effective future.
