Migrate Off Legacy — Without the Big Bang

Legacy identity platforms are expensive to maintain, hard to staff for, and increasingly unsupported. But ripping them out carries real risk — every downstream application depends on the auth layer working correctly.

DVLY has migrated identity platforms across industries — healthcare, financial services, government, SaaS. We plan migrations that keep your business running while moving you to Auth0, Okta, Cognito, or another modern platform.

IBM Security Verify (Tivoli)

Federated SSO, TAM/OIG migrations to Auth0 or Okta. User migration with policy preservation and access matrix mapping.

Microsoft B2C (Entra External ID)

Migration from B2C custom policies and user flows to Auth0 Actions, Okta Workflows, or Cognito Triggers. Social identity federation preserved.

Oblix (Oracle Access Manager)

Oblix/NetPoint/OAM migrations for enterprises still running Oracle identity stacks. Full session management and policy translation.

SiteMinder (Broadcom)

SiteMinder to Auth0 or Okta — including web agent policy migration, SAML/OIDC federation rewrite, and session domain restructuring.

User Migration

Bulk import with password hash preservation (bcrypt, PBKDF2, SHA-256). For legacy hashes we can't preserve, lazy migration hooks upgrade users at first login — zero friction.

Zero-Downtime Cutover

Dual-write and shadow mode strategies keep old and new systems in sync during migration windows. No big-bang cutover. No outage.

Migration Approach

Discovery & Assessment

We map your current identity topology — all consuming applications, federation partners, session policies, and custom logic. This becomes the migration blueprint.

Parallel Run

New platform runs alongside legacy for a defined period. Users authenticate through both, and we validate parity before cutover. This eliminates the "hope it works" phase.

Phased Cutover

Applications migrate in batches — not all at once. We prioritize by risk and dependency, starting with lower-risk apps and working toward mission-critical systems.

Post-Migration Hardening

After cutover, we harden the new platform: MFA policies, adaptive auth, SCIM provisioning, and monitoring. The job isn't done when migration finishes — it's done when the new platform is battle-tested.

Frequently Asked Questions

How long does a typical legacy identity migration take?

A standard migration from SiteMinder, B2C, or IBM takes 8–16 weeks depending on the number of consuming applications, federation complexity, and whether password hash preservation is possible. Simple migrations (few apps, standard federation) can complete in 6 weeks.

Can you migrate password hashes so users don't have to reset?

Yes. We support bcrypt, PBKDF2, and scrypt hash migration. For legacy hashes we can't preserve (DES, MD5, NTLM), we deploy lazy migration hooks that silently upgrade passwords at next login.

What if we have hundreds of applications integrated with the legacy platform?

We handle large-scale migrations through phased cutover — applications migrate in priority batches. Each batch is validated independently before moving to the next. We've managed migrations with 200+ consuming applications.

Do you handle the application-side changes or just the identity platform?

We handle both. Application-side changes (SDK swaps, redirect URI updates, token validation changes) are part of the migration scope. We coordinate with your development teams or handle it directly depending on engagement structure.
