A Strategic Comparison
Build vs. Buy: Migrating Audit Trails
Evaluating the total cost, risk, and time commitment of migrating legacy audit logs to an immutable blockchain ledger.
| Key Factor | Build In-House | Partner with Chainscore |
|---|---|---|
Time to Production | 6-12 months | 4-8 weeks |
Initial Development Cost | $150K - $400K+ | $50K - $150K |
Security & Audit Overhead | High (Requires external audit) | Included (Pre-audited patterns) |
Ongoing Maintenance | 2-3 FTE Engineers | Fully Managed Service |
Compliance & Proof Generation | Manual, error-prone process | Automated, court-admissible proofs |
System Uptime SLA | Your responsibility | 99.9% Guaranteed |
Integration Complexity | High (Custom connectors) | Low (Pre-built adapters for SAP, Oracle, etc.) |
Total Cost of Ownership (Year 1) | $300K - $700K+ | $75K - $200K |

Our Phased Migration Methodology
We execute legacy system integration with a structured, four-phase approach designed to eliminate downtime and ensure data integrity. Each phase includes defined deliverables, security checkpoints, and rollback procedures.
01
Phase 1: Discovery & Audit Trail Mapping
We conduct a comprehensive audit of your existing transaction logs, APIs, and data schemas to build a complete migration blueprint. This phase identifies all critical data flows and dependencies.

Phase 2: Non-Destructive Data Mirroring
We implement real-time, read-only data replication from your legacy system to the new blockchain ledger. This creates a verifiable audit trail without impacting your live operations.

Audit Trail Migration & Integration
Frequently Asked Questions
Common questions from CTOs and technical leads about modernizing legacy audit systems with blockchain.
A complete migration from a legacy system to a blockchain-based audit trail typically takes 4-8 weeks. This includes a 1-week discovery and planning phase, 2-4 weeks for core development and data migration, and 1-2 weeks for testing, deployment, and handover. For complex systems with multiple data sources, we break the project into phases to deliver value incrementally.
