Migrate Without Breaking Anything

Deploy Keymate alongside your existing IAM system-allowing seamless token exchange, login bridging, and gradual onboarding without service disruption.

Run Keymate Side-by-Side with Your Legacy IAM

Why It Matters

IAM migration is notoriously risky. Downtime, broken integrations, or partial user data can impact hundreds of systems. Parallel IAM Migration ensures:

Key Components:

Zero-downtime rollout

Gradual application onboarding

Real-world testing of sessions, roles, and access flows

Smooth handover from legacy IAM without breaking tokens or user workflows

Legacy & Modern IAM in Harmony

How It Works:

Use Cases Include: Phased IAM modernization projects, Co-existence with internal or vendor-built IAMs, External login via national systems or SSO bridges, Smoother testing before decommissioning legacy IAM

Key Components:

Users log in via Keymate OR legacy IAM (e.g., LDAP, homegrown systems)

Token Bridge: Existing tokens (e.g., JWT, session ID) are validated & exchanged for Keymate/Keycloak tokens

New users created on-demand in Keycloak if they do not exist

Session and role data mapped and enriched in Keymate

Applications gradually migrate to use Keymate as the primary IdP

Migration Enablers - What Makes This Work

Token Exchange SPI

Converts legacy IAM tokens to Keycloak-compliant tokens

External Login Authenticator

Session Sync SPI

Sync session/logout state across both IAM platforms

User Auto-Provisioning

Create Keycloak user profiles on first login

Attribute Mapping

Map user/org/role data from external IdP or directory

Delegation & Context Support

Preserve context like impersonation or "hat"-based access

Frequently Asked Questions

No. The framework is generic. We have integrated with custom-built IAMs, e-Devlet logins, and LDAP backends.

No. Token validation and mapping can be done via SPI plugins and custom authenticators.

You can fully disable the legacy system and continue using Keymate with confidence.

Yes. Mappers support importing usernames, orgs, roles, and even impersonation details.

How to Use This Deployment

Implementation Steps

Enable external login/authenticator SPIs in Keycloak

Configure token exchange flow with subject token validators

Implement session note and token mappers for attribute enrichment

Onboard apps gradually with fallback to legacy IAM

Monitor login telemetry and switch traffic step-by-step

Decommission legacy IAM when all systems are validated
