Microsoft Entra ID → Okta migration playbook
Migrate workforce IAM from Microsoft Entra ID to Okta — typically driven by best-of-breed identity strategy, Conditional Access complexity, or a multi-vendor commercial pivot.
TL;DR
Entra → Okta is the less-common direction (most enterprises move toward Microsoft for cost), but it does happen. Drivers: best-of-breed IAM strategy, Okta's broader pre-built integration catalog, or specific feature requirements Okta serves better.
Microsoft Entra ID
Okta Workforce Identity Cloud
Typical timeline
4-8 months for a mid-large enterprise
Why teams move
- Best-of-breed IAM strategy — picking Okta over the Microsoft default
- Conditional Access policy complexity that Okta's rules engine handles more cleanly
- Broader Okta Integration Network catalog vs Entra ID Gallery
- Lifecycle Management features (Okta Workflows) for advanced JML automation
The migration in 4 phases.
1. Phase 1 — Discovery
4-6 weeks
- App catalog inventory (SAML, OIDC, password-vault, manual)
- Conditional Access policy export
- Privileged Identity Management (PIM) policy inventory
- Decision on AD sync direction (keep on-prem AD with Okta AD Agent, or push to cloud-only)
2. Phase 2 — Okta foundation
4-6 weeks
- Okta tenant configured (Org, custom domain, branding)
- Okta AD Agent installed (or HRIS-driven JML)
- MFA + Conditional Access policies replicated
- PIM equivalent (Okta Workflows + Access Requests) configured
3. Phase 3 — App migration (cohorts)
3-6 months
- Apps re-federated to Okta in cohort waves (10-50 apps per wave)
- SCIM re-pointed where applicable
- User communication + training per cohort
4. Phase 4 — Decommission Entra
1-2 months
- Entra ID retained for Microsoft 365 only (federated to Okta)
- Or full Entra decommission if M365 is also migrated to Okta-managed
What lives where.
| Capability | Source (Microsoft) | Target (Okta) |
|---|---|---|
| MFA | Entra MFA | Okta Verify Re-enrollment required |
| Conditional Access | Entra Conditional Access | Okta Network Zones + Sign-on Policies |
| PIM | Entra PIM | Okta Workflows + Access Requests |
| B2B | Entra External Identities | Okta B2B |
| SAML / OIDC apps | Enterprise Applications | Okta Integration Network |
| Lifecycle (JML) | Entra provisioning | Okta Lifecycle Management + Workflows |
What moves, what doesn’t.
Users
Source from HRIS (or on-prem AD via Okta AD Agent). Don't try to "migrate" Entra users directly — re-source from authoritative HRIS.
Groups
Group definitions can be exported from Entra via Graph API, then recreated in Okta. Membership flows from AD or HRIS.
Microsoft 365
Most enterprises keep Entra ID as the source of M365 identities + federate to Okta for sign-in. Full Entra removal is possible but rare.
The 7-step cutover.
- 01Per cohort: dual-trust window (both Entra + Okta valid)
- 02Communicate the new sign-in URL + MFA re-enrollment
- 03Re-federate apps via SAML metadata swap
- 04Cut access via Entra after cohort completes
- 05Final wave: Microsoft 365 SAML federation Okta → Entra (or keep Entra IdP for M365)
What teams find out the hard way.
Microsoft 365 is the hard part
Most non-Microsoft apps move easily. M365 federation to a non-Microsoft IdP is possible (federated identity) but requires careful handling of conditional access on Microsoft's side.
PIM equivalence
Entra PIM is well-developed for just-in-time admin elevation. Okta's equivalent (Workflows + Access Requests) requires more configuration to match feature parity.
Licensing economics
Entra ID P1/P2 is often bundled with M365 E3/E5. Moving to Okta means paying for both. Run the TCO carefully before committing.
Questions we get on this migration.
Should we decommission Entra entirely?
Almost never. M365 + Azure resources need Entra. The practical pattern is "Okta for SSO across the app portfolio + Entra for M365 + Azure native."
How long does the project take?
4-8 months for a mid-large enterprise, depending on app catalog size and M365 entanglement.
