Legacy Migrations: Key Challenges and How to Avoid them

Today’s modern, technology-driven world has aided businesses in countless ways and necessitated many changes for companies to keep up with this ever-evolving market. Legacy application migration is daunting for many organizations, often presenting significant challenges that can lead to project failures. Despite recognizing the benefits of modernizing outdated systems, businesses often struggle to successfully navigate the complex landscape of legacy migrations. Understanding the common pitfalls and learning from past failures is crucial to avoiding the same fate. Cloud migration, i.e., moving apps, digital assets, and data from an on-premise infrastructure to a cloud platform, has been an integral part of this change. What may be even more interesting to note is that cloud migration plays a crucial role in the process of legacy app modernization, which, before you ask, involves transforming and updating a company’s current legacy apps to use modern capabilities and technologies. For legacy app modernization, cloud migration provides a scalable, flexible, and cost-effective environment for running and eventually enhancing such legacy apps. Unfortunately, the endeavor to migrate one’s legacy applications to the cloud often results in failure. I would not want your efforts to meet the same fate. Therefore, I’ve compiled a list of some of the key reasons affecting the legacy migration process and how to deal with it.rnIn this blog, I’ll explore why some legacy migrations fail and, more importantly, how you can steer clear of these pitfalls. So, let’s get started.

Reasons Why Legacy Migrations Fail & How to Avoid Them?

• Deficient planning: A lack of or insufficient planning can lead to suboptimal outcomes and delays and a variety of other problems, such as cost overruns, during the migration project. Thankfully, it is simple enough to deal with this challenge: start with assessing the legacy apps to understand their complexity & specific migration needs. It is also imperative that the team tasked with the migration process also sets out unambiguous goals and objectives for the migration process.
• Faulty cost estimates: It should go without saying that migrating legacy applications to the cloud involve various cost factors, such as data transfer, infrastructure, ongoing maintenance & licensing. Unfortunately, arriving at an accurate cost estimate for the migration can be challenging since several factors can affect the cost. So, how does one contend with this challenge? A good starting point would be analyzing the organization’s existing infrastructure costs and then comparing them with the estimated costs of running applications on a cloud platform of your preference.
• Wrong migration approach: Given that there are many different ways to migrate legacy applications to the cloud, it can be confusing to decide which option is best suited for your project’s unique requirements. Typically, the ideal approach for a given organization will depend on the specific needs of the applications and the organization. Also, assess different migration strategies, such as rehosting, refactoring, rearchitecting, or rebuilding, based on the desired outcomes, the app’s complexity, requirements, etc.
• No or improper employee training: It does not take a genius to see why offensive or no training would be problematic. You see, unless employees are properly trained on the new cloud-based applications, they will not be able to use said apps and tools effectively, thus leading to customer dissatisfaction, losses in productivity, etc. So, invest in upskilling and training programs that help familiarize employees with cloud computing, best practices, and cloud tools.

As you can see, folks, legacy application migration to the cloud offers organizations an effective way to transform and modernize their existing software systems. All you need for success is carefully planning and executing the migration.
