FGA Migration Overview

Comprehensive guide to migrating from legacy authorization systems to Fine-Grained Authorization (FGA) without rewriting applications

Fine-Grained Authorization Migration Platform

Modernize your authorization infrastructure without the massive rewrite. Authonomy’s FGA Migration Platform provides a comprehensive solution for organizations looking to move from legacy authorization systems (RBAC, hardcoded permissions, database-level access controls) to modern Fine-Grained Authorization (FGA) models.

The Authorization Migration Challenge

Most organizations struggle with authorization technical debt:

  • Legacy systems with hardcoded user lists and all-or-nothing access
  • Mixed authorization models across different applications and databases
  • No central policy management leading to inconsistent security postures
  • Compliance gaps due to inadequate audit trails and access reviews
  • Development bottlenecks when trying to add new authorization features

Traditional approaches require massive application rewrites that take years and cost millions—if they’re even feasible.

Authonomy’s Comprehensive Solution

Our FGA Migration Platform takes a fundamentally different approach: modernize authorization infrastructure without touching application code.

Key Platform Components

🔍 Discovery & Intelligence

  • Automated scanning of applications, databases, and configuration files
  • Complete authorization landscape visualization
  • Migration complexity assessment and effort estimation
  • Ongoing monitoring of authorization changes

🔄 Policy Translation & Modeling

  • Extract implicit policies from legacy systems
  • Convert between RBAC, ABAC, and ReBAC models
  • Generate optimized FGA policy models
  • Handle complex business rules and edge cases

âś… Migration Testing & Validation

  • Shadow mode testing in production environments
  • Side-by-side comparison of legacy vs. FGA decisions
  • Automated regression testing and performance validation
  • Zero-risk validation before enforcement

🛡️ Flexible Policy Enforcement

  • Network Gateway/Proxy: API and web application protection
  • Database Proxy: Row-level security and query rewriting
  • Library Integration: Framework-specific adapters and runtime injection

🔄 Synchronization & Consistency

  • Real-time permission synchronization across systems
  • Change data capture (CDC) for legacy databases
  • Bidirectional sync options with conflict resolution

Migration Methodology

Our proven 6-phase approach minimizes risk and ensures success:

  1. Discovery & Assessment - Understand your current authorization landscape
  2. Model Design & Translation - Convert legacy policies to modern FGA models
  3. Infrastructure Setup - Deploy enforcement components
  4. Shadow Mode Testing - Validate decisions without enforcement
  5. Gradual Rollout - Progressive migration with rollback capabilities
  6. Full Migration - Complete transition to FGA with legacy decommission

Quick Assessment

Answer these questions to understand your migration complexity:

  • How many different authorization models do you currently use?
  • Do you have legacy systems that can’t be easily modified?
  • How critical is maintaining 100% backward compatibility during migration?
  • What compliance requirements do you need to meet?
