Migration Guides

Purpose

This page provides reference-only guidance for migrating from prior schemas, platforms, or integration patterns to GMG Engine–compatible structures. It describes common considerations and checks without asserting data correctness, completeness, continuity, or successful outcomes.

This page is descriptive and informational only and must not be interpreted as a guarantee, certification, endorsement, or system-wide migration assurance.

How to Read These Guides

Migration steps and examples are illustrative. They highlight typical transition concerns and decision points, not mandatory procedures or success criteria.

Completing described steps does not imply that migrated data is correct, consistent, compliant, or production-ready.

Scope of Migration

Migration may involve schemas, identifiers, balances, event histories, configuration data, or integration endpoints. Each component must be treated independently with its own validation assumptions.

No assumption should be made that all historical data can be mapped one-to-one without loss, transformation, or reinterpretation.

Versioning and Compatibility

Migration guidance is scoped to specific schema versions and interface contracts. Version changes over time may invalidate earlier instructions.

Backward compatibility, forward compatibility, and deprecation timelines must be treated as configuration- and deployment-specific, not universal guarantees.

Data Interpretation Boundaries

Migrated records represent transformed representations of prior data, not authoritative restatements of historical truth.

Differences discovered during migration must be treated as indicators requiring contextual analysis, not as definitive errors or system faults.

Operational Considerations

Migration may require pauses, staged rollouts, parallel runs, or reconciliation periods. These are operational choices and must not be interpreted as guarantees of continuity or zero disruption.

External dependencies (networks, providers, legacy systems) may introduce timing or consistency constraints outside GMG Engine control.

Disallowed Inferences

Do not infer data correctness, financial accuracy, or settlement finality from migration completion alone.

Do not infer compliance, audit readiness, or regulatory suitability from the presence of migration documentation.

Do not infer equivalence between legacy behavior and post-migration behavior unless explicitly validated per component.

Common Failure Patterns

Treating schema compatibility as semantic equivalence.

Assuming historical data can be reinterpreted without loss of context.

Using migration success as proof of operational or financial correctness.

Boundary Conditions

This page does not define authoritative data sources, settlement rules, accounting logic, or enforcement behavior.

It does not replace independent validation, reconciliation, testing, or operator-specific review procedures.

Non-Goals

This page does not guarantee successful migration, data integrity, operational continuity, or user-facing outcomes.

It does not provide legal, financial, or compliance advice.
