What Next Pathway's Legacy Modernization Checklist covers
Rationalizing legacy sprawl means knowing what to keep, what to retire, and what to rebuild. This checklist walks the three phases that get you there — map the estate, define your data products, then build them. Any source, any target.
The Enterprise Intelligence Graph
Before rationalization, the entire estate is unified into one contextual intelligence layer: ETL transforms mapped to fields, semantic models and lineage, access and usage logs, and documents and SOPs connected to code. Redundancy detection identifies duplicate workloads and reduces costs before migration.
Data Product Definition
Usage logs identify workloads for rationalization into modular data products. Redundant and dead workloads are flagged for retirement, while active workloads are scored by usage, schema, business rules, and consumption. Clear retirement criteria prevent scope creep, and each product serves multiple consumers.
Build
Our SLMs generate cloud execution code, run automated testing to confirm analytical parity, and pass each product through engineering review before CI/CD. Data quality and governance criteria are defined upfront, with post-launch usage tracking to confirm adoption.

What a Structured Cloud Migration Covers
A successful cloud migration requires a clear plan across four disciplines — any source, any target.
Discovery and dependency mapping
Every table, job, report, and dependency scanned and cataloged into one contextual intelligence layer — column-level ETL logic, semantic model and lineage, real access and usage logs, and the documents and SOPs around the code. Partial visibility creates surprises later.
ETL strategy and sequencing
Decide upfront whether pipelines are rewritten natively or repointed, and base scope and sequencing on actual access and lineage data rather than assumptions. This single decision changes effort across the whole migration.
Automated code translation
Legacy SQL, stored procedures, and complex ETL translated automatically onto your target platform, following its native syntax and conventions. 100% automated code coverage, zero manual intervention, 100% of core business logic preserved.
Testing, parity, and cutover
Build the test plan before any code is translated. Automated testing frameworks and data validation prove 1:1 functional parity before production — with business users and SMEs defining success criteria so parity is judged against real usage.
