What is Legacy System Migration?

What is legacy system migration? In today’s modern era, every business must keep up with the latest technology to remain competitive.

Many organizations keep their old applications, systems and processes running for a long time, known as legacy systems.

Legacy systems can benefit businesses by allowing them to maintain continuity and keep their existing investments, but they can also cause problems.

As technology advances and new systems and applications become available, legacy systems can slow down businesses’ processes, become outdated and cause compatibility issues.

However, some applications and operations are deeply embedded into the organization’s infrastructure, making it difficult and costly to replace them.

To solve this issue, companies undertake legacy system migration.

Legacy system migration enables organizations to work with existing systems and migrate them to new technology and software without replacing their entire infrastructure.

In this blog post, you’ll explore various aspects of legacy system migration, including why it is necessary for businesses. So, let’s dive into it.

What is Legacy System Migration?

Legacy system migration is the process of transferring data, applications, and processes from older systems to new technology.

It usually involves analyzing existing systems, identifying and migrating data, applications, and processes, testing new systems for compatibility, ensuring data security, and monitoring the system after migration.

Legacy system migration is essential for businesses to stay competitive and reduce costs.

The new technology and systems can provide more efficient processes, fewer system errors, and improved user experience.

Migrating to a modern system can help organizations meet customers’ needs and expectations as customers increasingly demand better customer experience.

It can result in improved customer satisfaction and increased revenue for the business.

Types of Legacy System Migration

Legacy system migration is of two types. Here is an overview of each type:

Lift and Shift Migration

This type of migration involves transferring an existing system to a new platform without making any changes.

For example, if your company has an Android app and wants to shift it to iOS, you don’t need to build an iPad app.

You can lift the existing app, transfer it to Apple’s App Store and make it available for iOS users.

It is the simplest form of legacy system migration and involves minimal effort and cost.

In this approach, the entire system is moved from one platform to another without making any changes.

Data and resources are copied and lifted from the source system to the target platform.

This type of migration is crucial when the current system is outdated and needs to be replaced.

It only affects the IT infrastructure. It doesn’t impact your company’s development processes or business processes.

Business Transformation Approach

This type of legacy system migration involves making changes to the source system and the target platform.

This approach requires more effort than the lifting and shifting method but offers more significant benefits.

The main goal of this approach is to improve the company’s business processes and development workflow.

The source system is assessed during this approach, and all its components are evaluated for migration.

The system is then restructured and adapted to its new environment with the help of tools such as data integration, application modernization, process automation, and custom development.

Why Should You Invest in Legacy System Migration?

Legacy system migration has become increasingly important for businesses.

Here are some reasons why you should invest in legacy system migration:

Effective Cost Management

In business, your budget and financial resources are limited. You have to spend every penny wisely to maximize your profits.

Legacy system migration can help you save money in the long run. It eliminates the need to replace the entire system, which would otherwise be very expensive.

By migrating your systems to newer technology, you can reduce overhead costs, improve system performance and reliability, and ensure that your systems are up to date with the latest technology.

Better Data Protection

Data security is a major concern for businesses. By migrating to a modern system, you can ensure that your data and customer information are secure.

The new system also makes monitoring and responding to potential security threats easier.

Locally hosted systems are often outdated due to a lack of sufficient updates.

Moving your systems to cloud-based platforms is essential as they are more secure and offer better protection.

With a modern system, you can ensure that your data is encrypted and stored securely.

Improve Application Availability

Legacy systems can become outdated over time.

They slow down and take too much time to process data, which affects the overall system performance.

It will result in application and service unavailability.

By migrating to a modern system, you can increase the availability of applications and services.

The new system will be faster and more reliable, resulting in improved system performance.

Moreover, legacy systems are often not mobile-friendly.

They are difficult to use on multiple devices and platforms, which makes it harder for employees to stay connected while they are on the go.

By migrating to a modern system, you can ensure that your systems are accessible from any device or platform.

It will improve employee productivity and collaboration.

Solve Compatibility Issues

Legacy systems can often become incompatible with other software and devices.

It could lead to several problems, such as data loss or system malfunctions.

Migrating to a modern system can help you solve these compatibility issues.

You will be able to use the latest technology and applications, improving your system performance.
