A faster road off legacy is open.
Cloud migration run as one governed operation: extraction, translation, validation and cutover on a single runtime.
Causeway Moves the Whole Stack at Once
One governed crossing for the entire migration lifecycle.
Move the data, translate the code, retire the legacy stack, and stand up new operations in months, not years, at a fraction of the cost.

MIGRATION, THE OLD WAY
Half a Year of Planning Years of Execution Budgets That Balloon
WITH NRY CAUSEWAY
40 Minutes to a Plan Weeks to Cutover 10x Lower Cost
A real migration is never just data. It is decades of custom code to understand, values to convert, business units to merge, and every record proved against the compliance rules before anything can be switched off.
The classic programme splits that work across contractor teams that share neither tools nor context. Every failed check disappears into the gaps between them, and weeks go missing tracing a single broken record.
The result: the budget goes on coordination, the company stays dependent on outside integrators, and the move to the cloud never quite arrives.
Causeway holds the full picture for the whole crossing. Think of an octopus: eight arms working on their own, one brain keeping them coordinated. Specialised AI works each stage of the migration while one context engine keeps the legacy structures, the target schemas, the business rules and the compliance limits in view.
The difference: a failed check is traced to its source the moment it appears, corrected once, and the fix flows through every later step on its own.
No more validation loops. Feedback lands in minutes, not committee cycles.
Read & Absorb
Causeway takes in the data dictionaries, the legacy documentation, the business requirements and the compliance frameworks in one pass. Your environment is understood in hours, not quarters.
Query & Map
It queries the source systems directly, finds the real relationships between tables, and assembles the full data model of the stack on its own.
Translate & Prepare
AI-driven pipelines map the legacy values onto the target standards, build the transformation logic, translate the old code, and stage validated data for cutover.
The Bar for Cloud Migration Just Moved
99.4% First-Pass Fidelity
Validation fidelity passed 96% in the first days on-site and reached 99.4% inside two weeks.
Six-Month Plans → 40 Minutes
A full migration plan generated in forty minutes. Execution starts the same morning.

Company after company has crossed inside a working week, data, code, and cutover included.
The Early Crossings: Companies Already Migrated, Live in Cloud
Legacy Codebase Triage & Cleanup: Choosing the Target Before Moving
Millions of lines of dead logic retired
Migration scope cut by 60%
A carrier operating across Europe needed off its ageing ERP but had not picked a target platform, and refused to pick one blind. The stack held millions of lines of custom logic tied to live orders, and data carrying twenty years of exceptions.
Causeway ran an AI-driven inventory that brought the stack into focus within days. Roughly half the rules were dead and were flagged for retirement, and thousands more collapsed into a few hundred. With the custom logic mapped to live orders, retirement ran clean with no disruption, and the trimmed scope fed straight into scenario models of the true cost of each candidate platform.
The carrier's own engineers worked inside the process, validating findings and owning the high-risk seams. They chose their platform on evidence, not faith.
