ETL
ETL stands for Extract, Transform, and Load. It is an industry standard process used to move data from a legacy system to a target system.
The ETL process is essential in data migration because it helps ensure that data from the source system is not only transferred accurately but also aligned with the data model and format of the target system.
We have our own process , ACE Data, for ensuring this is done accurately and effectively. ACE Data is an approach, not just a process. It allows the project team to have confidence that the transform and load stage of ETL will go as smoothly as possible.
Extract
Data is extracted from the legacy system so it can be manipulated ahead of the migration.
Transform
Transformation can involve cleaning, filtering, aggregating, and restructuring data. This step ensures that the data is in the right format and structure for the destination system.
Load
The final stage sees the data loaded into the target system for future use across the organisation.
Our process.
Strategy
Strategy: Every successful migration starts with a clear strategy. We define objectives, data scope, assess data sourcing & quality, and identify key risks early on. This foundation, based on the binary10 methodology, ensures the project aligns with your organisation’s goals and sets the stage for a smooth migration journey.
Planning
We turn strategy into action with detailed planning. This includes scoping, timelines, resources, and stakeholder alignment, ensuring the DM Plan dovetails with overall programme milestones. A solid plan keeps the project on track, ensures accountability, and prepares teams for every stage of the migration.
Hypercare
In the days and weeks after go-live, we offer hands-on support. We investigate any issues raised swiftly to determine if they are data-related, work to resolve any issues quickly, monitor any data updates, and provide reassurance to users, helping them feel confident with the new system from day one.
Cutover
The final step is switching fully to the new system. We will manage the planning of DM Cutover tasks and coordinate with you to ensure these tasks sit correctly in your overall cutover plan, in order to minimise issues or disruption during the cutover period. With all tasks and checks complete and users supported, the cutover marks a clean handover and the start of real business benefits.
Reconciliation
We validate that everything has landed correctly from a technical viewpoint. Record counts, field-level checks, and audit trails are used to compare source and target data, giving you confidence that nothing was lost, changed, or duplicated in the process. We also manage the business reconciliation approach to ensure you have a structured plan for reconciling the data yourself, with your SMEs (Subject Matter Experts) fully briefed on the “what, when and how” they should carry out reconciliations.
