Okta to Microsoft Entra ID Migration Guide

A planning sequence for moving applications, identities, access, and provisioning from Okta to Microsoft Entra ID without discovering the hard parts halfway through.

How do you migrate from Okta to Microsoft Entra ID?

Inventory the Okta estate by protocol and owner, decide the treatment for every object category against a Microsoft Entra ID target, translate policy intent into Conditional Access, rebuild provisioning connections, then move applications in approved waves with Okta live until each wave has been validated and cutover is accepted.

Step 1

Inventory before anything else

An accurate inventory is the difference between a wave plan and a wish list. Group applications by protocol first, because protocol decides the target pattern, then by owner, because owner decides how fast a change can be coordinated.

  • Applications by protocol: SAML, OIDC and OAuth, SWA or password-based, and anything else.
  • Application owners and vendor contacts for each integration.
  • Users, groups, group rules, and how assignments are actually granted.
  • Sign-on policies, MFA factors, and network zones.
  • Provisioning connections, directory synchronization, and lifecycle automation.
  • API clients, scripts, hooks, and reporting pipelines that depend on Okta.

Step 2

Follow the protocol path

Target pattern by protocol.
ProtocolTarget patternWhat to watch
SAMLEnterprise application with SAML SSOEntity ID, reply URLs, certificates, and claim names
OIDC and OAuthApp registration plus enterprise applicationNew client identifiers, redirect URIs, and secrets
Password-based or SWAEntra ID equivalent where one existsSome applications need a different approach entirely
Legacy or header-basedApplication-specific architectureNo direct equivalent, plan separately

Step 3

Federation and domains

Where Okta federates a domain for Microsoft 365, the change from federated to managed authentication is a distinct piece of work with its own risk profile. Plan it as its own wave, with its own validation and its own fallback position, rather than folding it into an application wave.

Step 4

Provisioning is rebuilt, not moved

  • SCIM connections are recreated as Microsoft Entra provisioning, with attribute mappings re-tested.
  • Directory synchronization is redesigned around Entra Connect or Entra Cloud Sync.
  • Deprovisioning behaviour is confirmed explicitly, because the failure mode is silent.
  • Joiner, mover, leaver automation is reviewed against target capability before the switchover.

Step 5

Translate policy intent

Okta sign-on policies and Conditional Access are different models. Write down what each policy is trying to achieve, express that intent in Conditional Access and authentication method settings, then validate the outcome per application instead of assuming the translation held.

Step 6

Waves, validation, and cutover

  • Build waves around owner, risk, protocol, and the business calendar.
  • Give every wave entry criteria, exit criteria, and a fallback position agreed before it runs.
  • Validate sign-in, assignments, claims, policy behaviour, and provisioning per application.
  • Accept, remediate, or fall back as an explicit decision, and record it.
  • Retire Okta only when every dependency has a confirmed owner and replacement.

Object by object treatment is set out in the migration map.

Okta migration questions

How long does an Okta to Entra ID migration take?
It depends on application count, protocol mix, provisioning integrations, and how many applications need vendor coordination. Timelines are set from the inventory produced during assessment rather than estimated up front.
Do passwords migrate from Okta to Microsoft Entra ID?
Passwords are not moved between platforms. Authentication in the target uses Microsoft Entra ID authentication methods, which is why the authentication method design belongs in the Prepare stage.
Can Okta and Microsoft Entra ID run at the same time?
Yes. Applications move in waves, so Okta keeps serving anything not yet cut over. Coexistence is normal for most of the project.
Do Okta sign-on policies convert to Conditional Access?
Not directly. The policy intent is translated into Conditional Access policies and authentication method settings, then validated per application.
