Do you know some of the biggest enterprise mainframes are still running on legacy systems? Well, it is not surprising with the high cost of replacing these IT infrastructures. However, disruptive technologies like cloud computing have necessitated companies to adapt to remain competitive.
The modernization process has seen most of the companies run a hybrid system which in turn improves overall performance. With the emergence of various companies offering legacy modernization services, choosing the right one that can provide the best services for your firm is essential.
To avoid being overtaken by technology, this guide offers tips for the best modernization services in 2023.
What is Legacy Modernization?
A legacy system refers to outdated or old applications, hardware, and related IT infrastructure that is still in use. Therefore, legacy modernization is restructuring the system code to enable compatibility with the new platforms. That said, leading mainframe modernization companies offer these services to ensure enterprises maintain or improve performance.
To find a good modernization company, it must understand the system, evaluate it and determine the best approach. This will help in carrying out all the necessary tasks without issues.
Benefits of System Modernization
Now that you know what modernization is, does it have any benefit? Well, upgrading your mainframe offers many benefits, like the ones highlighted below.
- Low Risks and Fast Implementation
Modernization of mainframe and legacy systems usually involves low risks. There are no significant changes, meaning the business continues to run smoothly, even during the implementation phase. The digitization duration is also short, taking less than 12 months for small firms, hence a worthwhile investment.
- Improved Reliability and Performance
Upgrading the mainframe and other IT infrastructure is one way to improve reliability and performance. Typically, these upgrades avail more resources, making the system more reliable and faster.
- Cost Reduction
The cost of running legacy systems is higher due to many maintenance requirements. However, rehosting and modernization have helped companies to cut the running cost by up to 50%. This is a significant cost reduction, considering the system is more efficient and reduces maintenance labor costs.
- Improved Security Compliance
The implementation of new technology in your system improves security. This is because the new system offers state-of-the-art protection lacking in the old, outdated legacy systems.
- Added Agility
By upgrading the mainframe and legacy systems, there is improved agility. The system can allow the addition of new apps to fit the company and consumer needs, like the use of mobile apps and social media, among others.
In 2023, understanding legacy modernization is crucial for businesses seeking to stay competitive in a rapidly evolving digital landscape. To embark on this transformative journey, individuals and organizations can find mentors who possess expertise in legacy modernization.

Why Are Legacy Systems Challenging to Modernize?
Although there are many experts in this field, modernizing legacy applications and other systems brings serious challenges. That is why there is a need to look for a qualified company that can handle the task without issues. Some of these challenges are listed below.
- Complex Data
One of the challenges when modernizing a legacy app is the massive amount of complex data from the old systems. The data poses a challenge as experts can take a long time to extract and figure out how to integrate it with the latest technology.
- High implementation cost
Although companies save a lot after modernizing, initial implementation is costly. The requirements for new infrastructure, personnel, and labor require serious investment.
- Slow to Implement
Due to the outdated nature of legacy systems, it might be slow to implement due to inefficient processes. Depending on the size, some can take a year or more to implement.
- Risks
Migrating from old to new systems comes with some risks. Some data might be lost during migration, compromising the system or causing failures. This increases the workload as experts try to fix the system.
- Limited Resources
Most of the legacy systems require people trained to operate them. With most experts specializing in newer systems, these outdated systems lack enough people to maintain them. Also, only a few people understand the old and new systems, making rehosting challenging.
Tools and Features for Modernization
Many resources are needed to make the process successful during the modernization process. These are the tools and features that are required to implement the strategy.
- Assessment
Before any move, the system assessment is one of the first steps to determine the right approach. Companies use various methods to assess, analyze, and formulate the data extraction and migration process. Through the use of application intelligence services, the company can determine the best approach.
- Refactoring
Refactoring involves the use of digital and manual tools to accelerate modernization. Usually, the tools used help in refactoring legacy system languages, modernizing app software stack, and creating macroservices and microservices.
- Replatforming
It involves converting some systems like COBOL, NATURAL, and PL/1 into a cloud-based system. Usually, the process aims to port the legacy coding without changes and integrate it into the cloud system. This helps preserve the firm code and language by modernizing it without modification to enable seamless transition without affecting the normal user experience.
- Replication of Data
Data replication involves files and other important information from the mainframe into the cloud. This is usually a real-time operation that doesn’t affect the business operations. Companies can enjoy improved, digitized, fast processes with successful data replication.
- Developing IDE
System modernization usually offers an integrated development environment whereby data transferred is cleaned, debugged, and unit tested.
Implementing the Best Practices for Legacy Modernization
If you want to upgrade your legacy system and maintain its performance, these are some of the best strategies.
- Prioritize Modernizing Vulnerable Apps
When modernizing the mainframe and other systems, it’s ideal to keep analyzing and checking the vulnerable ones and prioritize which one to modernize first.
- Plan For Digital Migration
Planning for digitization of legacy systems is essential in increasing performance. Usually, before deciding to implement, conduct a thorough analysis, evaluation, and other needed tests to determine the right approach.
- Opt for Cloud Based Services
These days, cloud services are offering fantastic experiences. Instead of expensive hardware upgrades, leveraging cloud services offers fast performance, agility, and cost-effectiveness.
- AI Testing Solution
After digitizing the services, it’s essential to evaluate the performance. Automated testing solutions and AI can significantly boost live system evaluation.
- Continuous Assessment And Updates
Giving the system a continuous assessment to determine its integrity is vital for security. Also, updating is essential since it solves any performance issue.
- Look for Reliable Vendors
Different companies offer cloud services. Therefore, selecting the ideal vendor with excellent services and reliability is paramount. Besides providing great services, they will assist in everything needed for legacy modernization.
- Be Future Proof
It is always essential to think about the future. Therefore, when modernizing, always put into consideration future changes. Be sure your system can adapt to changing trends and accommodate them comfortably.
Conclusion
System modernization is essential and inevitable to keep up with the ever-changing business trends. While it might be challenging and costly, the process is vital. Using the best approach, digitizing your system while maintaining the same user experience is possible.
Having an excellent company to implement the change ensures your enterprise enjoys amazing technology and a modern feel.
