Okta to Microsoft Entra ID Migration Center¶

The definitive resource for migrating from Okta Workforce Identity Cloud to Microsoft Entra ID, with CSA-in-a-Box as the identity governance and data platform integration layer.

Who this is for¶

This migration center serves identity architects, security engineers, IT directors, IAM analysts, and federal identity teams who are evaluating or executing a migration from Okta to Microsoft Entra ID. Whether you are responding to Okta security incidents, eliminating duplicate identity costs, consolidating around the Microsoft security stack, or meeting federal identity consolidation mandates, these resources provide the evidence, patterns, and step-by-step guidance to execute confidently.

Quick-start decision matrix¶

Migration approach decision¶

Before beginning, select the migration model that fits your organization:

Option A: Full replacement (recommended for M365-native organizations)¶

Complete Okta decommission. Entra ID becomes the sole identity provider. All SSO, MFA, provisioning, and lifecycle management move to Entra ID.

Best for: Organizations with M365 E3/E5 licensing, primarily Microsoft-stack applications, and a mandate to reduce identity provider count.

Timeline: 24-32 weeks.

Option B: Coexistence (transitional)¶

Okta and Entra ID coexist for an extended period. Entra ID handles Microsoft-stack authentication; Okta handles third-party SaaS. Federation links the two.

Best for: Organizations with large Okta application portfolios that cannot migrate all apps quickly, or those with Okta-specific features (Workflows with non-Microsoft connectors) that require replacement planning.

Timeline: 32-52 weeks, with ongoing dual-IdP operational cost.

Option C: Phased replacement (recommended for large enterprises)¶

Full replacement executed in waves. Wave 1 migrates Microsoft-stack apps and high-risk apps. Wave 2 migrates SaaS apps. Wave 3 migrates custom apps and completes decommission.

Best for: Enterprises with 200+ SSO applications, regulated industries, federal agencies with change control requirements.

Timeline: 40-52 weeks.

How CSA-in-a-Box fits¶

CSA-in-a-Box is not an identity provider. Microsoft Entra ID is the identity provider. CSA-in-a-Box is the data platform landing zone where identity consolidation unlocks tangible operational benefits across every platform component.

Migration timeline¶

A realistic full-replacement migration for a mid-to-large enterprise runs 28-32 weeks:

Okta security incident context¶

Okta has experienced multiple security incidents that have eroded customer confidence, particularly in regulated industries:

• **January 2022 (Lapsus\():** Threat group Lapsus\) compromised an Okta customer support engineer's workstation. Okta initially downplayed the incident, then disclosed that approximately 2.5% of customers (roughly 375 organizations) were potentially affected. The delayed and incomplete disclosure damaged trust.
• December 2022 (source code theft): Okta's private GitHub repositories were accessed by unauthorized actors who copied source code. While Okta stated the breach did not impact customers, the compromise of source code for an identity provider is a significant supply chain concern.
• October 2023 (customer support system): Attackers gained access to Okta's customer support case management system, accessing HAR files that contained session tokens. The breach affected all customers who had opened support cases. Initial scope claims of 1% of customers were revised upward to 100% of customer support users.
• Broader pattern: Each incident followed a pattern of delayed disclosure and underestimated scope. For identity providers, which are the root of trust for entire organizations, this pattern is particularly concerning.

For federal agencies and regulated enterprises, these incidents have accelerated identity provider consolidation planning. This migration center provides the execution guidance to make that transition.
