Current-state assessment
Capture the current environment, dependencies, constraints and operating risks so decisions about current-state assessment are based on what actually exists.
Gromnii modernizes fragmented data estates without losing operational continuity.
Use data architecture and modernization when information is fragmented across legacy stores, duplicated models or brittle pipelines that cannot support new analytics and AI requirements. Modernization should preserve data meaning and operational continuity while simplifying how data is stored and served.
This reference shows one possible Data Architecture and Modernization arrangement. The actual design depends on the systems, constraints and controls involved.
Capture the current environment, dependencies, constraints and operating risks so decisions about current-state assessment are based on what actually exists.
Define authoritative domains, integration patterns, analytical serving layers and governance boundaries before moving data so the new platform has a clear operating model.
Map application, data and integration dependencies before migration and coexistence work begins.
Replace brittle legacy structures with stable business definitions and versioned schemas while preserving the mappings needed for phased migration.
Stage Cutover planning so old and new paths can be reconciled while critical work continues.
Compare source and target counts, keys, relationships and business totals during migration, and resolve mismatches before the new platform becomes authoritative.
Plan migration windows around dependent reports, integrations and applications, with clear rules for what can pause and what must remain continuously available.
Preserve recoverable source data and reversible migration steps until reconciliation confirms that the target architecture is producing correct results.
Assign decision owners for source systems, target models and migration exceptions so unresolved data conflicts do not stall the modernization.
Reduce unnecessary duplication and one-off movement patterns by defining clearer source, storage and serving responsibilities.
Plan schema changes, reconciliation, coexistence and rollback so modernizing data does not corrupt dependent reports or applications.
Create data structures and interfaces that can serve analytics, applications and AI without rebuilding the foundation for each use case.
Describe what Data Architecture and Modernization should change, the systems it must work with and the constraints that matter.
