    Do You Follow These Best Practices in Application Migration?

    4 Minutes Read

The current pandemic scenario that has taken the world by storm increases the need to be agile and adjust to a fast-changing business environment. A cloud-based environment is, indeed, the foundation of a more adaptive IT environment. Migrating to the cloud is a key enterprise-wide change that needs a well-thought-out strategy. After all, legacy application migration can be hard. This creates the need to hire an application migration consulting team with a very high level of technical acumen and expertise. They are well aware of the challenges faced while migrating legacy systems to the cloud and follow best practices to ensure a smooth transition.

What are application migration services?

The procedure of shifting an application program from one environment to another is known as application migration. When the current applications fail to offer the flexibility and scalability required to meet the requirements of modern-day businesses, there arises a need to conduct the application migration process.

Organizations move their existing applications to the public cloud, private cloud, or hybrid cloud environments to accomplish the desired scalability and resiliency. Application migration services and tools enable consulting companies to plan a well-orchestrated migration strategy for your business and move your applications to faster workloads with zero risks and minimal costs.

Application Migration Tips

Maintain Systems Running in Parallel

As you move your aging systems and applications to the cloud, it is critical to keep the old system running. It can continue to offer value to your business while the new platform is being built from the ground up to avoid any kind of operational stop. When you keep systems running in parallel, you leave the existing application as-is without breaking the current functionality. Doing so also leads to less effort in re-testing the entire existing application after it is modified.

Recognize All Data Inputs

It can be quite time-consuming to understand the intricacies of legacy systems. IT leaders with experience in legacy migrations should be able to recognize all the data inputs as well as the places where they need to send the data. There may be data with many fields, a few of which won’t need to be mapped to the target system.

Besides, there may be missing data fields within a source. Ask yourself what needs to migrate over, what could be missing, and what can be left behind. Run an audit on the actual data contained within. Not only does the data become more effective this way, but also this practice saves a lot of time.

Get Operations Right

Organizations that adopt DevOps prove to be more efficient in the migration of legacy applications. Experienced CTOs and CIOs believe that focusing on building a continuous integration/continuous deployment (CI/CD) platform acts as an enabler for the development team. Create monitoring alerts and a good logging system to keep the development team accountable for their work and fix potential issues faster and proactively.

A well-conceived CI/CD pipeline is a very popular approach to baking automation into the several phases of your development and deployment processes. A CI/CD pipeline enables you to automate steps in your software delivery process. These steps include initiating code builds, running automated tests, and deploying to a production or staging environment. Through automated pipelines, you can eliminate manual errors, allow product iterations, and provide development feedback loops that are standardized.

Use Microservices The Right Way

As the monolithic application is broken down into loosely coupled and independently deployable services that are organized around business capabilities, you should use them the right way. Only then can you handle different problems with different approaches.

Microservices enable you to use different data models, improve individual scalability, de-risk any performance issues, work parallelly, build, test, and deploy quicker, as well as provide value faster, with you being able to release partial features of your modernized system in isolation. As you deploy microservices in containers, you can improve reliability, traceability, and portability too.

Shift Security Left

Pay special attention to modernizing security practices as you containerize applications in agreement with Kubernetes. Kubernetes enables you to manage containers at scale. Note that security needs to be built into your development processes as soon as possible. As you move to the cloud, new technologies can challenge your current approach to security.

Data collection and network security solutions, thus, should adapt to an ephemeral environment where applications come and go. One of the best practices here is to never patch a running container. Experts advise organizations to revisit their investment in DevOps and in shifting security left.

Are your legacy application migrations in place?

If you find your legacy systems slowing down organizational change or obstructing productivity, you will face growing competition from newer companies that follow digital-first operating models. Remember migration of applications is crucial to enable companies to stay in business and ahead of their competition. If you follow these best practices when modernizing your legacy apps and opting for managed cloud services, you are sure to reduce infrastructure costs significantly and drive huge profits.
