The digital world today demands speed and higher performance to remain competitive. With the obsolete legacy systems, it is hard to meet the modern world requirements, as they are built upon old technologies. Hence, migrating systems to the cloud is preferable, especially after COVID and minimizing scalability issues. With legacy systems migration, you can modernize your old IT setup to an all-new software and hardware infrastructure.
This blog post will discuss the necessary steps needed for migrating legacy systems to the cloud to get optimum performance and boost your business.
Why Should You Migrate Your Legacy Systems to the Cloud?
Businesses require a modern and flexible system that can adapt to the current technologies. The legacy system migration is initiated when the current system performance is not up to the mark. Cloud migration is important to keep up with the current market but has risks involved too. Hence, companies looking to make a move also need to consider that the migration is risk-free and no data is lost in the process.
Steps to Migrate Legacy Systems to the Cloud
No doubt, cloud computing has revolutionized businesses and accelerated their growth manifolds. Hence, migrating to the cloud will be profitable in the long run. Legacy applications include everything from in-house developed applications to customized ones. Transitioning to them can be challenging, but with these steps, you can make a smoother and successful shift giving your business a completely modern outlook.
- Step 1: Perform an Audit
Before moving to the cloud, it is foremost important to understand your business systems. Drawing up a list of your current infrastructure and applications will help. Evaluate each application - if it is cloud-friendly or needs restructuring? You will also find some applications that are not worth migrating, as they will incur high costs and hold no business value. Make sure to remove those applications. Identify the systems to be intertwined and keep a check on the dependencies.
- Step 2: Make an Estimation
After the audit, the next step is to evaluate your business infrastructure for a subtle cloud migration plan. With proper assessment and planning, understand the scope of migrating your physical and virtual workspaces to the cloud. You can hatch out a plan based on the company infrastructure, network architecture, organizational capacity, resilience, and performance considerations. All of these can be determined with workloads, applications, and processes you are using currently. With a plan, you can also discover the maintenance processes for your new cloud environment.
- Step 3: Choose the Migration Strategy
With the action plan ready, it is time to choose the migration strategy suitable for your business. You can pick from the three strategies described here:
- Making a Shift: This strategy is the simplest, where you copy everything to the cloud as it is. It is less tedious but is a huge waste of resources and costly due to over-data usage.
- Modifying Application: In this strategy, you spot the parts of the application you will switch to the cloud. You can migrate to the cloud in sections, but this can be expensive as well.
- Redesigning Application: In this method, the application is disintegrated and rebuilt in a scalable and modern design. You need not code the application that restrains your business agility. This is one of the best options and relevant to the business.
- Step 4: Execute Test Migration
In this step, you will deploy a migration for testing to know if your migration is not obstructing your day-to-day functions. Here, you will see how users are interacting with your new environment. You can also fix some areas before the final migration launch. Initial testing can be time-consuming but will involve the users examining the application to check if it is working normally.
But, it is a worthwhile step, as you will identify the potential risks before the actual migration is settled.
- Step 5: Execute Actual Cloud Migration
After the complete assessment and preparation of workloads and applications, now is the time to migrate your legacy system to the cloud. Before migration, you should back up all your data to avoid losses that could happen during the process. After the migration is accomplished, check that you have all the data present in the system and the users can access the cloud applications as before. Cloud migration is a lengthy process and needs expertise. Hiring the right solution provider will be worth your efforts.
- Step 6: Monitor Cloud Resources
You have not finished even after migrating the legacy systems to the cloud completely. After the movement, applications hosted on the cloud need regular monitoring and optimization to make the most of the cloud resources. You should also keep track of the cloud usage to avoid paying extra storage charges for services you are not using. With the availability and usage reports, you can avoid paying for idle cloud resources and pay as you go cloud computing.
Legacy systems migration to the cloud can improve the performance and competency of your organization. With poor system performance and higher maintenance costs, migration becomes essential. Without adapting to modern technologies, the existing systems cannot be up to date with the same speed and demand innovation. Therefore, cloud migration from legacy systems is the best step for an organization's smooth functioning. We hope the steps given above will serve as the best guidance for successful cloud migration in your organization!
