Ragnarok
Migration Orchestration for ERP Replacement
The execution engine of the Mimir platform. Ragnarok replaces legacy ERP systems with structured, validated data transfer into Yggdrasil — preserving business meaning across the transition.
Why ERP Migrations Fail
The industry treats migration as a data-moving problem. It’s not. It’s a meaning-preservation problem.
Manual Mapping
Migration consultants spend weeks building spreadsheets that map source fields to target fields. Every mapping is a guess informed by tribal knowledge. When the consultant leaves, the rationale leaves with them.
Data Loss by Default
Legacy systems encode business meaning in ways that don’t translate directly — status codes, implicit relationships, overloaded columns. Without structural understanding of both systems, meaning is lost in transit.
No Structural Validation
Traditional migrations validate row counts and spot-check values. They don’t verify that the data landed in the right structural context — that relationships are intact, that referential chains are complete, that business objects survived the translation.
Scope Uncertainty
Most migration projects can’t answer basic coverage questions until they’re halfway through. How much of the source was mapped? What was left behind? What landed in the wrong place? The answers come too late.
The Migration Experience
From legacy system discovery to governed data transition — what your organization receives.
Source system understanding
Ragnarok connects to your legacy ERP and builds a complete structural map — every table, column, relationship, and data type classified and scored.
How Ragnarok Changes Migration Outcomes
Ragnarok is purpose-built migration infrastructure — not a collection of scripts, not a consulting methodology wrapped in software. It understands both sides of the migration: where your data lives today and exactly where it belongs in Yggdrasil.
Complete Visibility Before Execution
Before any data moves, Ragnarok produces a full migration plan: what will be transferred, what requires attention, what gaps exist, and what the coverage posture looks like across every business module. Decisions are made with full information, not during a crisis.
Semantic Fidelity, Not Just Row Counts
Legacy ERP vendors encode business meaning in proprietary ways — status integers, compound keys, overloaded type columns, implicit relationships. Ragnarok resolves these into Yggdrasil’s deterministic schema, ensuring that business objects arrive structurally intact and semantically correct.
Accelerated, Not Automated
Ragnarok accelerates expert judgment. It proposes, scores, and prioritizes — but every mapping decision is reviewable by your team before execution. The system handles the structural complexity so your people can focus on business decisions.
Migration Capabilities
Semantic-Aware Migration
Ragnarok understands the business meaning of your source data, not just its shape. Migrations preserve semantics — not just rows and columns.
Deep Source Knowledge
Pre-built knowledge of 10+ legacy ERP platforms. Ragnarok arrives with an understanding of SAP, Epicor, Oracle, NetSuite, Dynamics, Infor, Sage, Acumatica, and TeamCenter data models.
Deterministic Targeting
Every piece of source data is mapped to a specific location in the Yggdrasil schema. No ambiguity, no orphaned records, no “we’ll figure it out later” columns.
Full Coverage Reporting
Before a single row moves, you know exactly what will be migrated, what won’t, and why. No surprises at go-live.
Structural Integrity
Data arrives in the correct relational context. Parent-child relationships, foreign key chains, and business object hierarchies are preserved throughout the migration.
Human-in-the-Loop
Ragnarok proposes. Humans decide. Every mapping is reviewable and overridable before execution. The system accelerates expert judgment — it doesn’t replace it.
Supported Source Systems
Ragnarok includes deep, pre-built knowledge of the following legacy ERP platforms and their data architectures.
Additional source systems supported through structured onboarding.
The Mimir Platform
Discover. Migrate. Sustain.
Ragnarok is not a standalone tool. It is the execution layer of a platform designed to make ERP replacement predictable.
Ratatosk
Semantic Discovery & Ontology Alignment
Maps the meaning of your existing data landscape. Surfaces definition conflicts, aligns cross-department taxonomy, and produces the governance baseline that Ragnarok consumes as its source of truth.
Ragnarok
Migration Orchestration & System Transformation
Consumes what Ratatosk discovered. Orchestrates the structural transformation from legacy to Yggdrasil. Produces validated, relationally complete data in the target schema.
Bifrost
Live Data Bridge & Continuous Alignment
Maintains alignment after migration. Persistent, event-driven synchronization ensures that once systems are aligned, they remain aligned — continuously and deterministically.
The End of Your Legacy System
Ragnarok exists because ERP replacement shouldn’t require a leap of faith. When you can see exactly what will happen before it happens — when every mapping is visible, every gap is quantified, every business object is accounted for — migration becomes an engineering problem instead of a political one.
