The world of data is changing. Over the past decade, the amount of data available has grown exponentially, to the point that most companies can’t even keep track of it all.
This has created a need for a new generation of data management solutions, one that can handle and store massive amounts of data in various formats, sometimes across multiple platforms.
With so many options out there, how do you choose the right solution?
In this post, we’ll walk you through the process of choosing a legacy migration solution, from the initial planning stage all the way through to implementation, as well as some of the solutions available such as Pillir Low-code migration.
Legacy Migration: What Does it Mean?
A legacy system means outdated computing hardware or software that is presently in use. Although these IT systems might still comply with the requirements that they were initially developed for, they usually rely on old technologies that can be harder to find now.
Legacy migration solution means the modernization of the old systems to a novel software platform or hardware infrastructure.
Why Do I Need to Migrate My Business from Legacy Systems?
When you migrate from legacy systems to a cloud platform, it can enhance the competitiveness and performance of your business. Legacy systems often experience many problems such as poor system performance and high maintenance costs.
Moreover, being incompatible with the latest technologies could result in difficulties when changing these IT systems because they can’t be updated at the same rate as the business is changing or innovating.
Lack of regular updates and vendor support for older systems can also compromise the security of your business data. That said, migration from old systems is essential for ensuring an effective IT system.
A legacy system migration needs an easy-to-update, modern and flexible system that can quickly adapt to day-to-day changes with minimum interference to the ongoing business activities. System migration is the process of moving old systems to more recent software platforms or hard infrastructure to keep up with the current trends in technology.
Forms of Legacy System Migration
There are two main forms of legacy migration solution – ‘lift-and-shift’ legacy system migration and transformation legacy system migration:
- Lift-and-shift legacy system migration. This means migrating the entire application as well as its associated data to a cloud-based service without redesigning the application. This form of legacy system migration is usually started by the IT department of a company when the present IT system fails to deliver as expected, if a recent technology with a quicker processor is available or when the current IT system becomes obsolete.
- Transformation legacy system migration. On the other hand, transformation legacy IT migration is typically pushed by changes in the direction of a particular company or when the old system inhibits user experience or cannot support your business processes.
Steps Involved in Migrating from Legacy Systems
1. Understand data, location, sensitivity and format
The first step of the data migration process is to understand what data you’ll be moving, its present format and the intended format post-migration. If you intend to move sensitive files, you want to ensure that all the security protocols and guidelines have been adhered to.
2. Identify financial, technical and time requirements
Here, you must be realistic when making your estimations. Carry out every step at a time to avoid any costly errors. From source data to configuration, make sure that you take some time to understand all the aspects. Legacy system migration processes tend to be lengthy and could require input from IT, finance and engineering departments to determine the technical and budgeting aspects of this project.
3. Back up all the organization’s files and data
It’s important to save all the essential files should a system crash take place. You should develop a detailed risk assessment report and the inventory of your business assets to monitor in the event any compliance issues arise.
4. Execute the migration plan
Carefully carry out all the steps stipulated in the data migration strategy.
5. Test the IT system after every step of the migration process
Ensure that the system migration has successfully worked. Test for data integrity and minimal downtime. Also, make sure there’s no lost data and the apps function fully post-migration.
