My Work

What I do

As a data migration specialist, I help clients transition their data from a source system to a target system efficiently and securely. Every migration is unique, and I tailor my approach to meet each client’s specific requirements, ensuring data integrity and minimal downtime.

Assessing

The first step in any migration is selecting the right approach. I assess the source and target environments, identify potential risks, and choose the best tools and strategies to facilitate a smooth transition.

Planning

Before migration, I perform a comprehensive assessment of the client's existing data environment, focusing on:

  • Understanding the source and target systems
  • Identifying data structures and dependencies
  • Defining mapping specifications for transformation
  • Analysing workload patterns and performance requirements
  • Planning budgets, timelines, and resource allocation

During this stage, I use Teamwork, a project management tool, to communicate with clients by creating Development Quality Requirements (DQRs).

Schema and Code Migration

I manage schema and code migrations, ensuring that database objects, SQL scripts, ETL processes, and business logic are accurately converted to the target system. Automated tools assist in the conversion, but I always review and validate the output to maintain functionality.

Data Migration and Synchronisation

Once the schema is in place, I migrate the data while ensuring consistency and integrity. Test Loads in a sandbox environment allow clients to visualise their data in a staging area before executing the full migration.

The migration strategy depends on:

  • Database size and complexity
  • Rate of data change
  • Allowed downtime and business constraints

Testing & Updating

During this stage of the migration lifecycle, communication with the client is essential. Even after the Test Load, updates and fixes are implemented to help achieve a closer alignment with the client’s vision for their production system. Multiple test loads can be performed depending on the complexity of the client’s data and specific requirements.

I also provide assistance to the client with using the new system by providing insights and knowledge.

Go Live & Ongoing Support

Once the testing stage is complete, the migration to the production system begins. This phase involves executing the final data load, performing integrity checks, and ensuring a smooth transition with minimal disruption to business operations.

After the migration, I provide ongoing support to address any post-migration issues, assist users in adapting to the new system, and ensure data consistency. Any necessary refinements or additional data adjustments are made to align with evolving business needs.
