Data Migration: A Key to Seamless Digital Transformation

With the increasing usage of advanced technologies, the need for efficient management of information has become prominent for businesses today. The global data migration market is predicted to reach 25.2 billion US dollars by 2030 and generate an impressive CAGR of 18.4% between the years 2024 and 2030. This remarkable growth is a burgeoning one, as businesses are doing away with the on-premises systems and are moving to the cloud for reasons of better operational performance and cost. As companies find more and more advantages from using data, the process of data migration is now a common practice within the digital transformation processes of firms as it allows companies adapt to new market trends and adopt new technologies. ?

Data migration can be defined as the transfer of data from one database system to another. This may be from Oracle to MySQL or from Oracle to a service managed in the cloud. It requires precise guidelines to account for variations in data types and schema designs.?

Example: Cloud Amazon RDS receives patient medical records of a healthcare provider in compliance with HIPAA.?

3. Application Migration?

Application migration means transferring software applications and their data from one environment to another, from in-house to the cloud. Consideration of application dependencies and data types is essential.?

Example: A company transitions from in-house ERP to SAP S/4HANA Cloud for easy access.?

4. Cloud Migration?

Cloud migration is the process of moving data, applications, and business elements to, from, or between clouds. It is usually motivated by scalability and cost-effectiveness.?

Example: A media company moving its digital asset management system to Microsoft Azure to enhance collaboration.?

5. Business Process Migration?

Business transfer also involves moving all aspects of the business process, including data and applications, to another system. It involves technical migration, modification of the original workflow, and user training.?

Example: An organization transferring its CRM system to an online management system for foreign clients’ relations.?
