Organisations embarking on a digital transformation will need to consider moving data at some point.
You may be modernising your architecture, consolidating a range of databases or simply wanting to reduce your total cost of ownership by changing to a more affordable provider. However, database migrations have become increasingly more complex in recent years, making the prospect of moving your data a potentially risky endeavour.
When a database is migrated to a new system, some of the data may not migrate over from the source system. Even when the database migration process is performed efficiently, semantics errors can occur where information from certain fields could be migrated over into a different field in the target system. Unwanted data can also be migrated into the new system, causing potential crashes and data corruption, which results in frequent errors for end users.
The biggest risk to avoid is the extended downtime when the database migration process takes longer than expected. This is perhaps the key reason many CIOs delay or avoid database migrations, even when they understand the business benefits of migrating to a better performing system.
With architectural differences between relational and other databases, legacy data migration can be complex, but a well-defined database migration strategy will enable you to mitigate every possible risk. By first setting up a data governance process, you’ll be putting the project in position to effectively handle any issues that arise in change management, data quality, and data mapping conflicts. In these early stages, migration shouldn’t only be viewed as a technology exercise as features and functionality can be identified in the system for getting greater buy-in from business leaders.
Ultimately, your migration should be a repeatable process that’s executed in a controlled way. By looking at the business value required from your target platform, you can avoid making the target data just a replica of the source. Also, paying special attention to master data will enable you to remove redundancies during the migration process.
The key is to minimise the risks with careful planning, and maximise the results with skilful execution. Fujitsu has the database experts, tools and processes to ensure your data is moved quickly and efficiently, minimising the impact to your daily operations.
Fujitsu takes a collaborative approach to digital transformation. We work with you to determine the feasibility of transferring your data to PostgreSQL or FUJITSU Enterprise Postgres, develop a sound strategy for the execution, then take ownership of the actual migration process between databases through to providing support for your new environment. The migration process will also highlight any areas of application modernisation required as we have access to a team of experts who specialise in this area.
Our Migration Assessment service will highlight which SQL statements may need to be modified prior to transfer.
We can suggest how best to modify them then assist you to ensure a smooth migration. On completion of the migration we provide a comprehensive report verifying exactly what was in the original database, what was moved and what is now in your new database. This way all your data is accounted for throughout the process, providing genuine peace of mind.
A strong support element is essential to any successful migration. Our database experts are on hand to answer your questions and ensure peace of mind at every stage of the process. Call us on +612 9452 9191 if you would like to discuss how we can help you.
