Hire an identity engineering firm that will run the move as a staged coexistence program, not a cutover date. The right partner inventories every application, policy, and provisioning flow before touching anything, keeps Okta and Microsoft Entra ID authenticating side by side while applications move in waves, translates your Okta sign-on policies into Conditional Access with an explicit parity map, plans MFA re-enrollment as a managed program, and keeps a tested rollback path open for every wave. If a consultant proposes a single migration weekend, keep looking. i3solutions regularly delivers Okta to Microsoft Entra ID migrations for enterprises. Our engineers are senior, US based, and work from Microsoft’s documented migration guidance rather than improvised scripts, which is what keeps users signing in on Monday morning.
This page covers what to require from any partner you evaluate, the mechanics that prevent broken access, the licensing implications, and how we deliver these programs.
What the Right Migration Partner Looks Like
The failure mode in identity migration is always the same: something authenticated yesterday and does not authenticate today. Put these six items in your RFP and require specific answers, not adjectives.
- A staged coexistence plan, never a big bang. The partner should describe exactly how Okta and Entra ID will run in parallel: Microsoft Entra staged rollout to move pilot groups to cloud authentication while the domain stays federated, or Okta identity provider routing rules to send pilot cohorts to Entra ID while everyone else stays put. If they cannot name the coexistence mechanism, they have not done this before.
- A complete inventory before any cutover. Every SAML, OIDC, and OAuth application, every SWA password-vaulted app, every SCIM provisioning flow, sign-on policy, group rule, and admin role. Undiscovered dependencies are the number one cause of broken access, and discovery after cutover is called an outage.
- A Conditional Access parity map. Okta sign-on policies and Entra Conditional Access do not map one to one. Require a document that lists each Okta policy, its Entra equivalent, and every gap with a decision recorded. Report-only mode should be used to validate policies against real sign-in traffic before enforcement.
- An MFA re-enrollment program. Okta Verify enrollments do not transfer. Users must register Microsoft Authenticator, FIDO2 security keys, or Windows Hello for Business. A real plan covers communications, registration campaigns, helpdesk staffing for the enrollment window, and temporary access passes for users who get stuck.
- Break-glass accounts and rehearsed rollback. Microsoft’s own guidance calls for emergency access accounts excluded from Conditional Access and MFA. Beyond that, every migration wave needs a tested way back: re-federate the domain, re-point the application, restore the routing rule. Ask the partner to describe the rollback for a failed wave. Hesitation is your answer.
- Licensing mapped before design, not after. Conditional Access requires Entra ID P1. Risk-based policies and Privileged Identity Management require P2. A partner who designs policies your licenses do not support is handing you a surprise renewal conversation.
The Mechanics of a No-Broken-Access Migration
These programs succeed in phases, and the order matters.
1. Discovery and dependency mapping. Pull the full application list from Okta, classify each app by protocol, identify which have Entra gallery equivalents and which need custom app registrations, and map every provisioning flow and group rule. This phase also surfaces the apps nobody remembered, which are precisely the ones that break.
2. Directory and authentication foundation. If Okta currently federates your Microsoft 365 domain, the first move is usually taking authentication for that domain back: Microsoft Entra Connect with password hash synchronization in place, then staged rollout to shift pilot groups to managed authentication while the domain remains federated for everyone else. Microsoft documents this path step by step for Okta-federated tenants, including the pilot group approach.
3. Application cutover in waves. SAML and OIDC applications are re-pointed to Entra ID one at a time: gallery app or app registration on the Entra side, metadata exchanged, a test cohort verified, then the general population. SCIM provisioning is reconnected so joiner, mover, and leaver events keep flowing. Waves run from low-risk apps to the business-critical core, so process problems surface where they are cheap.
4. Policy translation. Each Okta sign-on policy is rebuilt as Conditional Access: network zones become named locations, device trust becomes device compliance signals from Intune, and session policies are mapped to sign-in frequency controls. The honest version of this work produces a decision log, because some constructs have no direct equivalent and someone accountable has to choose the replacement behavior.
5. MFA re-enrollment. Registration campaigns run ahead of each user wave, so no one hits an MFA prompt they cannot satisfy. Done well, this phase is boring, which is the goal.
6. Validation and decommission. Sign-in logs are checked per wave against the pre-migration baseline, and Okta comes down only after a defined quiet period with zero unresolved authentication failures. Governance work such as access reviews and entitlement management starts here, once identities are consolidated. Our Microsoft Entra ID governance services pick up exactly at this point.
Why These Migrations Break Access
When we are brought in to stabilize a migration that went sideways, the cause is almost always one of five things: a big-bang cutover with no coexistence period, sign-on policies copied by name instead of translated by behavior, MFA factors that did not transfer and were never re-registered, SWA and password-vaulted apps that were never inventoried, or no break-glass account when a Conditional Access policy locked out the administrators who could have fixed it. All five are preventable in the first two phases, which is why we refuse to compress discovery.
What the Move Means for Licensing
Entra ID licensing is public and worth pricing before you commit. As of Microsoft’s current published pricing, Entra ID P1 lists at $7.00 per user per month and Entra ID P2 at $10.00 per user per month, both paid yearly. P1 carries Conditional Access, which the policy translation work depends on. P2 adds risk-based Conditional Access through Identity Protection and Privileged Identity Management for admin roles. Microsoft 365 E3 includes P1 and E5 includes P2, so many enterprises already own the entitlement they need and the migration consolidates spend rather than adding it. Your partner should model this against your actual agreement, not a list-price table.
Should You Migrate at All?
An honest answer first: not every organization should leave Okta. For some environments, particularly those with large non-Microsoft application estates or multi-cloud identity requirements, staying on Okta is the right call. We say that with a straight face because we implement and integrate Okta for clients where it is the right platform. The organizations that benefit from migrating are usually Microsoft-centric enterprises consolidating licensing they already own, unifying policy under Conditional Access, and reducing the number of identity control planes an auditor has to walk through. If you are still weighing the platforms themselves, our comparison of Okta vs Entra ID covers the decision in depth. Hire a partner who can argue both sides. A firm that only ever recommends migration is selling a project, not advice.
How i3solutions Delivers These Migrations
We deliver Okta to Entra ID migrations for enterprises in regulated and complex sectors, including aerospace and defense manufacturing, financial services, and healthcare. The work is led by senior US-based identity engineers, follows the staged coexistence model described above, and produces the artifacts your board and auditors will ask for: the application inventory, the Conditional Access parity map with its decision log, the wave plan with rollback procedures, and the validation evidence for each cutover. We run discovery first, we do not compress it, and we leave your team with documentation rather than dependency on us. Because we work across the Microsoft stack, the same team carries the downstream work: Intune device compliance signals for Conditional Access, and identity governance once the migration lands.
If you are evaluating partners, bring us your application count and your current Okta policy set. Schedule a Microsoft Entra ID Migration Consultation and we will walk through the wave plan we would propose and where the risk actually sits in your environment.
Frequently Asked Questions
How long does an Okta to Entra ID migration take?
It scales with the number of federated applications and the complexity of your sign-on policies, not your headcount. Planning and discovery typically run a few weeks; application cutover then proceeds in waves, each validated before the next begins. A large estate with custom SAML apps, SWA apps, and intricate policy logic takes longer, and compressing it is how access breaks.
Will users lose access during the cutover?
Not if the program is run on a coexistence model. Okta and Entra ID authenticate in parallel while applications move in waves, pilot cohorts validate each change before it reaches the general population, and every wave has a rehearsed rollback. The users most at risk are those with unregistered MFA factors, which is why re-enrollment campaigns run ahead of each wave rather than after it.
Do users have to re-enroll in MFA?
Yes. Okta Verify enrollments do not carry over. Users register Microsoft Authenticator, FIDO2 security keys, or Windows Hello for Business through Entra’s registration process, and temporary access passes cover users who hit trouble. Treat this as a managed campaign with communications and helpdesk readiness, not a mass email.
What Entra ID licenses do we need?
Conditional Access, which replaces your Okta sign-on policies, requires Entra ID P1. Risk-based policies and Privileged Identity Management require P2. Current Microsoft list pricing is $7.00 per user per month for P1 and $10.00 for P2, paid yearly, and Microsoft 365 E3 and E5 already include P1 and P2 respectively. Check your existing agreement before buying anything new.
Can we keep some applications on Okta?
Yes. The coexistence architecture that makes the migration safe also supports a deliberate hybrid end state, where a subset of applications stays on Okta long term. Most enterprises consolidate fully to reduce license spend and audit surface, but the wave model does not force that outcome. A good partner scopes the end state to your application estate, not to their statement of work.
