Legacy data silos
Critical information resides in multiple disconnected applications, making reporting and decision‑making error‑prone.
System Migration & Rescue
System Migration & Rescue
When a business outgrows its current platform, Nadmaa applies a business‑analysis first approach to map processes, then designs and executes a migration that preserves continuity and prepares the new environment for growth. Based in Calgary, we focus on the logic before the code.
In practical terms
What this service means at Nadmaa.
System Migration & Rescue is a service that extracts, transforms, and loads your existing data and processes into a new, fit‑for‑purpose system while maintaining operational continuity. Nadmaa begins by documenting every workflow, rule, handoff, record, exception, and permission. That map drives a migration plan that either re‑configures the target platform, builds connectors, or develops custom components where no existing solution fits. The result is a clean, documented, and fully operational system that matches the way your business works.
Where it helps
Problems this work is designed to address.
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
Concrete system and operating outputs.
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
Process first. Architecture second. Delivery third.
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.
Related thinking
Useful context before you make the technology decision.
Questions
What teams usually need to clarify.
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.
