Legacy System Modernization Strategies for Business Success – 8 Strategies Explained
Let’s take a look at these potential 8 strategies –
Strategy 1 – Establishing Clear Software Modernization Goals
To ensure successful legacy system modernization, merely migrating from COBOL/CICS (a 60-year-old programming language still in use) to Java is not sufficient. It is essential to link the modernization efforts to specific business and technological goals, such as scalability, incorporating additional features, and achieving quicker time-to-market.
Leveraging Modernization for Enhanced Customer Satisfaction and Cost Savings
For example, consider updating billing software and integrating it with a fresh e-commerce platform. This move can lead to increased client satisfaction and significant cost savings for the company. As a result, fewer clients may need to contact the company for bill-related issues, leading to a streamlined and efficient customer experience.
Assessing the Impact on Key Business Metrics
The impact of legacy software modernization on various aspects of the business, such as revenue, market share, and customer experience, depends on the industry, market conditions, and specific organizational goals. By conducting a thorough assessment, businesses can determine how modernization efforts will influence critical performance metrics and overall business success.
Strategy 2 – Identifying Legacy System Issues
An essential aspect of legacy application modernization is the thorough detection of bugs and deficiencies within the old system. If the current system fails to meet the organization’s current needs, it becomes imperative to delve deeper into the existing issues. Identifying the pain points experienced by users while using the digital solution is critical.
Leveraging User Stories for Improvement
Businesses should gather relevant user stories to gain insights into the specific issues faced by users. Understanding these user perspectives is instrumental in shaping the modernization plan and addressing user frustrations effectively.
Recognizing Legacy Software Strengths
In addition to identifying issues, it is equally crucial to recognize the strengths of the legacy software. Understanding what aspects of the current system work well provides valuable information for selecting the most suitable legacy modernization strategy.
Strategy 3 – Assessing Legacy Application Modernization Solutions
Modernizing legacy systems requires a systematic approach involving needs identification, current status analysis, assessment of modernization possibilities, and the implementation of a comprehensive modernization strategy. Among the available solutions, the top four legacy application modernization approaches must be considered.
Solution 1 – Replatform
The “Replatform” approach involves making minimal changes to the legacy system and migrating it to a different platform. While the code function and structure remain unchanged, this method allows hosting applications on a more cost-effective platform. It is ideal when only a few functionalities need modernization, migrating processes to the cloud is necessary, or there is a financial constraint.
Solution 2 – Reface
The “Reface” solution focuses on revamping the user interface of the legacy system by adding new graphical features. This approach saves on licensing costs and is suitable when the management has a strong association with the legacy application, the IT teams are highly skilled in the old technology and can make continuous improvements, or the technology base is relatively modern (e.g., J2EE/Java).
Solution 3 – Rebuild
In the “Rebuild” approach, the enterprise legacy system is rebuilt entirely, or specific core parts are reconstructed. Although extreme, this approach offers significant returns and a competitive edge. It is chosen when the current system cannot support market-demanded changes; the vendor no longer supports the underlying technology, or the present technology is prohibitively expensive to license.
Solution 4 – Extend and Migrate
“Extend and Migrate” is a well-strategized legacy software update method where the legacy system is gradually extended, introducing new features and modern applications step-by-step. This allows for updates without entirely replacing the legacy system, reducing the risk and business impact significantly. It is best suited when replacing the entire system incrementally, updating specific components, transitioning from batch to real-time processing, or modernizing an outdated database with an RDMS system.
Commonality in Enterprise Digital Transformation
In enterprise digital transformation processes, these four legacy application modernization solutions are frequently employed. Businesses can select the most appropriate approach according to their specific needs, technological capabilities, and strategic objectives.
Strategy 4 – Choosing the Optimal Legacy Modernization Architecture
After settling on a legacy modernization strategy, the next step involves carefully evaluating and selecting the optimal architecture for the application, database, and platform/server. This decision-making process takes into account a multitude of factors and trade-offs that can significantly impact the success of the modernization effort. The team must consider variables such as scalability, compatibility, performance, security, and cost-effectiveness, all while aiming to strike the right balance to ensure a smooth and successful modernization journey.
Cloud vs. On-Premises Platform/Server
The team needs to decide whether to host the platform/server in the cloud or within their data center. Cloud hosting can reduce capital expenditures (CapEx) while increasing operational expenditures (OpEx). On the other hand, hosting on-premises provides more control over the infrastructure. The decision depends on the organization’s budget, scalability needs, and data security requirements.
Database Selection: Open-Source vs. Proprietary
Choosing the right database is crucial for a successful legacy modernization. If the current program works well, the team may opt for a less expensive, open-source database like MySQL or Postgres. This may require re-platforming the program to make it compatible with the new database. The selection should align with the organization’s performance, scalability, and budgetary needs.
Full Cloud Migration Consideration
For a comprehensive modernization approach, organizations may choose to replace their data center with the cloud and migrate both the application and the database. While this offers long-term reduction in IT staff, it requires higher immediate costs. Organizations need to weigh the benefits of cloud migration against the upfront investment.
Aligning Architecture with Automated Processes
The chosen architecture must be aligned with automated processes such as DevOps, DataOps, and other pipeline delivery paradigms. These automated technologies enable acceleration and add value to modernization efforts. The enterprise architect is responsible for making informed decisions that accommodate these automated practices and support business goals.
Strategy 5 – Building the Right Modernization Team
For effective legacy application modernization, assembling the right team is crucial. The modernization initiative typically involves the following personnel hierarchy:
C-suite Executives
The program is led by C-suite executives, including the Chief Information Officer (CIO), Chief Technology Officer (CTO), Chief Information Security Officer (CISO), and Chief Security Officer (CSO). They provide strategic direction and oversee the modernization process.
Enterprise Architecture Team
This team receives reports from the C-suite executives and acts as a bridge between the IT and business teams. They ensure that IT capabilities align with business demands for goods and services. The enterprise architecture team plays a critical role in developing a comprehensive modernization plan that aligns with the overarching business goals.
Business and IT Teams
Both the business and IT teams serve as points of contact for their respective communities. They collaborate to ensure smooth communication and alignment throughout the modernization process.
Strategy 6 – Defining Success Metrics
Establishing success metrics based on the initial motivation is essential to evaluate the effectiveness of legacy application modernization. These metrics should be aligned with the specific goals set for the modernization initiative.
