Despite new technologies emerging every day, many organizations still rely on outdated software and hardware known as legacy systems. While these systems might have served well in the past, they can hinder growth and efficiency in the present day. As such, legacy system migration is a very prevalent concern within modern organizations, albeit not always the right choice. Let’s delve into what legacy systems are, the reasons behind legacy system migration, and how Alumio can ensure a seamless transition between old and new systems while reducing the risk of data loss.
The future of legacy systems
Legacy systems, once the backbone of many organizations' technological infrastructure are increasingly becoming outdated in our current fast-paced digital world. However, despite the advent of new technologies that promise enhanced performance and efficiency, legacy systems hold valuable historical data and critical business logic that are essential for ongoing operations. As businesses strive to integrate these older systems with cutting-edge innovations, they face a multitude of challenges. As a result, technologies that can swiftly integrate old systems with new ones without causing disruptions in the technological landscape are gaining popularity.
What are legacy systems?
Legacy systems are outdated computer systems, software, or applications that are still in use despite newer and more efficient alternatives being available. These systems often form the backbone of a company's operations but can be difficult and costly to maintain.
Typically characterized by outdated technology, legacy systems use old programming languages, software, or hardware; incompatibility due to the difficulty of integrating them with modern systems; high maintenance costs since they are expensive to maintain and upgrade; and limited scalability as they cannot support business growth or new functionalities.
However, it is important to know that not all legacy systems are obsolete technologies. In fact, most legacy systems are able to perform their duties despite being outdated, and enterprises will often continue using legacy systems that are critical to their daily functions and business needs for a diverse number of reasons.
What are the types of legacy systems?
The different types of legacy systems include mainframe computers, old ERP systems, proprietary software like custom-built applications that are no longer supported by the original developers, and outdated operating systems such as IBM AS/400, Oracle E-Business Suite, Windows XP, or older Linux distributions that are still in use for specific applications.
What is legacy system migration?
Legacy system migration involves the transferring of data, applications, and processes from outdated systems to modern platforms. This migration can involve moving systems from on-premises to a cloud infrastructure or simply modernizing old systems by updating the hardware infrastructure.
This process can be complex, requiring careful planning and execution to ensure minimal disruption and data loss. Legacy system migration typically includes data transferring from the old to the new system, application reengineering such as updating or rewriting apps to function on modern platforms, and system integration to ensure the new system connects seamlessly with the existing one.
Why should you migrate legacy systems?
While it is often a choice, migrating legacy systems is a cornerstone of digital transformation and a great option for organizations wanting to invest in a long-term, future-proof digital strategy. Here are some reasons why organizations migrate legacy systems:
Discontinued support or production: The most common reason behind legacy system migration is that the old system is so outdated that the software provider no longer provides support for it, is not available for purchase, or will depend on obsolete technology to run and maintain, which is known as EOL (End of Life).
Different technological needs and expectations: Another reason to migrate legacy systems is that the existing system is no longer functioning as planned and cannot accommodate an organization’s technological needs anymore.
Security concerns: Most legacy systems are overexposed to security vulnerabilities and are, therefore, targets for cyberattacks as they cannot be updated to comply with modern cybersecurity standards. This is mainly due to the fact that a lot of legacy software has undergone considerable patching to try to keep it up to date.
Better options on the market: It can also be the case that there are new technologies on the market that can perform tasks more efficiently and are perhaps a better choice for a future-proof strategy, as they will not become obsolete any time soon.
Over-spending: Due to their outdated nature, repairing and maintaining legacy systems is often a significant investment and will likely involve hiring highly skilled IT professionals to maintain them.
Why do organizations still use legacy systems?
This is a valid question. If a software or system is considered legacy, why would organizations keep using them? In the majority of cases, it is usually for one of the following reasons:
- They still function (albeit not perfectly)
Despite being outdated, many legacy systems and applications still work and are crucial to a business's daily functions. As such, wanting to replace systems and technologies that still function just because they are outdated is not always necessary, especially if a company does not have the budget for it.
- Lack of resources
The costs involved in replacing a legacy system or application can be significant, especially in the short term. In the long term, maintaining legacy systems will eventually cost organizations more money than migrating, but some businesses may simply not have the necessary resources available on short notice and, therefore, prefer to delay the migration process as much as possible.
- Lack of technical expertise
Modernizing legacy systems can be a complex undertaking, especially without the necessary in-house or outsourced technical expertise. Simply put, some organizations lack the required skills to modernize their systems and deal with the potential challenges that may arise from doing so, in which case, migration may not be an option for them until they are better equipped to handle it.
