Data migration is the process of transporting data between computers, storage devices or formats. It is a key consideration for any system implementation, upgrade or consolidation. During data migration, software programs or scripts are used to map system data for automated migration.

Data migration is categorized as storage migration, database migration, application migration and business process migration. These scenarios are routine IT activities, and most organizations migrate data on a quarterly basis.

Data migration occurs for a variety of reasons, including:

  • Server or storage equipment replacements or upgrades
  • Website consolidation
  • Server maintenance
  • Data centre relocation

It may impact business operations when it creates extended downtime, compatibility and performance issues. Organizations use various strategies to minimize such impacts, including effective planning, technology, implementation and validation.

Planning, migration and validation are key to effective data migration. Planning requires a clear understanding of design requirements, such as scheduling, replication requirements, hardware requirements, data volume and data value. Prior to data migration, an organization typically communicates methodologies, installs migration software and configures required hardware.

Automated data migration minimizes human intervention and application downtime and enhances migration speed. Migration documentation facilitates tracking and reduces future migration costs and risks.

Once data migration is complete, an organization validates statistics to determine data accuracy. Finally, data cleaning facilitates improve data quality via the removal of unnecessary or repetitive data.

Data Migration Helps in Technology

Technology has revolutionised society and it’s changed the way we live. As of 2012, the average Australian household had 2.53 computers (not including other smart devices). For a device that plays such a pivotal role in our lives, the majority of computer owners don’t fully understand the history of computing or how it evolved into what you’re looking at. Once we understand the history of computing, we can begin to chart the next step in the evolution process. This step involves the buzz words of the last few years – cloud computing and data migration.

Fast forward 25 years and we have a device that is incredibly fast, light and capable of running advanced software. Responsible for the third industrial revolution, the computer has a role to play in the next industrial revolution.

Many tech experts believe we’re in the midst of a fourth industrial revolution, one that’s centred around cyber physical systems and artificially intelligent devices. It’s expected that the next industrial revolution will incorporate a wide array of devices, not just computers. However, computers still have a role to play.

Currently, many companies are still running legacy systems. This means that data is stored natively, i.e. separately on each computer. This may include database records, spreadsheets, text files, scanned images or specific programs that must be installed on a device – think Microsoft Office CD’s.

Data migration is the process of importing legacy software/data to a new system. Importantly, this process allows businesses to migrate to the cloud. As we transition into the fourth industrial revolution, it will be critical for these smart devices to be able to access information hosted in cloud storage. As a result, if a business wants to utilise the technology/smart devices that will soon become available to society it needs to migrate to the cloud.
