Legacy data silos
Critical information resides in multiple disconnected applications, making reporting and decision‑making error‑prone.
System Migration & Rescue
Move the system without losing how the business works.
Plan migrations and rescues around the records, rules, integrations and controls that must survive the change, not only the data export.
In practical terms
Migration is an operating change, not a file transfer
A successful move preserves the information people trust, the controls the business depends on and the workflows that still need to work on day one.
Where it helps
Where migrations usually become risky
Manual, error‑heavy processes
Key activities rely on spreadsheets or paper forms, leading to rework and missed deadlines.
Platform incompatibility
Upgrades or new modules cannot be added without extensive custom code, increasing maintenance costs.
Risk of downtime during migration
Unplanned interruptions can affect customers and revenue if the migration is not carefully orchestrated.
What the engagement can produce
What we make explicit before the move
Consolidated data model
A unified schema that captures all required entities, relationships, and historical records.
Configured integration layer
Standardized APIs and connectors that enable real‑time data flow between the new system and existing tools.
Migration runbook with rollback plan
Step‑by‑step procedures, test cases, and a documented fallback strategy to ensure safe execution.
Post‑migration validation report
Evidence‑based verification that data integrity, business rules, and performance targets are met.
The method
How we reduce migration surprises
Discovery & workflow mapping
Interview stakeholders, capture process diagrams, and document rules, exceptions, and permissions.
Migration design
Define target architecture, data transformation logic, and integration points based on the mapped workflows.
Execution & monitoring
Run data extracts, perform transformations, load into the new environment, and monitor for errors in real time.
Stabilization & handover
Conduct functional testing, train users, and deliver documentation for ongoing support.

Questions
Migration and rescue questions
How does Nadmaa ensure data integrity during migration?
Migration validation should compare the records, balances, relationships and business rules that matter to the operation before and after conversion. Nadmaa defines those checks during assessment and rehearses them in a representative test environment before production cutover.
What if the new system cannot meet a legacy custom feature?
Our approach is to first assess whether the requirement can be satisfied by configuration or a standard connector; only when necessary do we develop a targeted custom module.
Can you migrate from on‑premise to cloud environments?
Yes. We can assess on-premise dependencies and design a staged cloud migration. The cutover plan should define acceptable downtime, rollback criteria, data validation and security controls before production is changed.

Show us what cannot afford to break.
We will map the dependencies, data and workflows first, then build a migration path that keeps the operation running.
