Copilot Studio Moves to Entra Agent ID

Disclaimer: I create this content entirely on my own time, and the views expressed here are mine alone (not my employer’s). Because I love leveraging new tech, I use AI tools like Gemini, NotebookLM, Claude, Perplexity and others as a “digital team” to help research and polish these articles so I can share the best possible insights with you!

I’ve been talking quite a bit about Microsoft’s massive effort to make Copilot a more usable and coherent platform. Piece by piece, Microsoft is bringing together agents, identity, security, governance, and management into a more consistent enterprise framework. The latest move is the rollout of self-service migration for existing Copilot Studio agents to Microsoft Entra Agent ID — and while it may sound like a small technical change, it points to something much bigger: AI agents are becoming first-class enterprise identities.

According to Microsoft 365 Message Center notification MC1462458, the gradual rollout began on August 24, 2026, through Power Platform Advisor. Copilot Studio agents created before May 2026 may still be using traditional app-registration identities, and Microsoft is recommending that organizations migrate eligible agents to Entra Agent ID.

At first glance, this may sound like a relatively minor identity-management change.

It isn’t.

This is another important step toward something enterprises increasingly need as AI adoption accelerates:

Agents need identities, permissions, governance, monitoring, and lifecycle management just like people and applications do.

With this change:

AI agents are becoming first-class enterprise identities — and they need to be governed that way.

What is Microsoft Entra Agent ID?

Microsoft Entra Agent ID extends Microsoft’s identity platform specifically to AI agents.

Historically, many agents have been represented inside Entra as conventional application registrations or service principals. They could authenticate and access resources, but from an identity-governance perspective they essentially looked like applications.

Agent ID changes that model.

Microsoft describes Agent ID as an identity foundation designed specifically for AI agents, allowing organizations to discover, govern, monitor, and protect agent identities across their environments.

For new Copilot Studio agents, Microsoft now automatically provisions an Entra Agent ID. Older agents may continue using their original app-registration identities until they are migrated.

That distinction becomes increasingly important as organizations go from experimenting with a handful of AI assistants to potentially operating hundreds or thousands of agents.

Why migrate existing Copilot Studio agents?

The real value is governance.

Moving an agent to Entra Agent ID brings the agent more directly into Microsoft’s identity and security ecosystem.

Among the benefits Microsoft highlights are:

• Audit logging in Microsoft Entra ID, providing better visibility into agent authentication activity.
• Agent lifecycle management, helping organizations manage agents from creation through retirement.
• Integration with Microsoft Entra ID Governance.
• Better visibility into connector permissions, with connector permissions appearing as API permissions associated with the agent identity.
• Conditional Access targeting, allowing organizations to apply policies based on factors such as network location, device compliance, or risk conditions.

That last point is particularly interesting.

As agents begin accessing enterprise systems, calling APIs, invoking workflows, retrieving organizational data, and acting on behalf of users, security teams will increasingly need to answer questions such as:

• Which agent accessed this system?
• What permissions does that agent have?
• Who owns it?
• Should it still have access?
• What happens when the employee who created it leaves?

Traditional application registrations weren’t designed around those questions.

Agent identity governance is.

What changed on August 24?

Microsoft’s August 2026 Message Center announcement adds an important operational piece to this transition.

The company began the gradual rollout of self-service migration through Power Platform Advisor on August 24, 2026.

Organizations with eligible agents can use the Power Platform admin experience to identify and migrate older agents.

Microsoft’s current documentation also states that older agents can be manually migrated using the Power Platform admin center, PowerShell, or Power Platform APIs.

For administrators, the Power Platform Advisor workflow is intended to make identifying and migrating those agents easier.

The general path described in the Message Center announcement is:

Power Platform admin center → Actions → Entra ID Governance → Active

From there, administrators can review the migration action and identify eligible Copilot Studio agents.

Don’t migrate everything at once

One of Microsoft’s more important recommendations is also one of the most practical:

Start small.

Instead of migrating every agent immediately, begin with a small batch of noncritical agents.

After migration, validate the complete agent experience, including:

• Channels
• Authentication
• Actions
• Connectors
• Power Automate flows
• Integrations
• Permissions

Then check Microsoft Entra sign-in logs and Conditional Access results before moving on to the next group.

If an agent doesn’t validate correctly, Microsoft recommends reverting it before continuing with additional migrations.

This is particularly important because an agent is rarely an isolated object.

A production Copilot Studio agent might connect to SharePoint, Dataverse, Power Automate, APIs, Teams, custom connectors, or other enterprise systems.

The identity may change behind the scenes, but the entire chain of dependencies still needs to work.

One important documentation caveat

Microsoft’s documentation around this transition has been evolving quickly.

Some earlier Microsoft guidance described a recreate-and-decommission process for Copilot Studio agents using legacy service principals, while newer Copilot Studio documentation now describes migration through the Power Platform admin center, PowerShell, and APIs. Microsoft’s August 2026 Message Center announcement adds the new Power Platform Advisor self-service migration capability.

For that reason, organizations planning a migration should check the latest Microsoft documentation and their own Power Platform Advisor experience before designing a migration process around older guidance.

This area is changing rapidly.

The bigger story: AI agents are becoming first-class enterprise identities

This is the part of the announcement I find most significant.

The enterprise AI conversation is rapidly moving beyond:

“Which AI model should we use?”

and toward:

“How do we safely operate an organization filled with AI agents?”

Agents won’t simply answer questions.

They will increasingly:

• access corporate information,
• call APIs,
• execute workflows,
• interact with applications,
• create and modify information,
• communicate with other agents,
• and perform tasks on behalf of employees.

Once agents can act, identity becomes foundational.

We already understand this concept for humans:

Identity → Authentication → Authorization → Governance → Monitoring → Lifecycle

AI agents need essentially the same discipline.

Microsoft Entra Agent ID is one example of that transition becoming part of mainstream enterprise infrastructure.

Where Agent 365 Fits In

The move to Microsoft Entra Agent ID is also part of a much bigger picture.

Microsoft is positioning Agent 365 as the centralized control plane for observing, governing, and securing AI agents across the enterprise. Entra provides the identity and access layer, while Agent 365 brings broader visibility, lifecycle management, policy enforcement, and governance across an organization’s growing agent population.

That relationship is important:

Entra Agent ID answers “Who is this agent, and what can it access?”

Agent 365 answers “How do we manage, govern, monitor, and secure all of our agents at scale?”

Microsoft’s direction is becoming increasingly clear: as agents become part of everyday work, organizations will need the same disciplines around identity, ownership, lifecycle, security, compliance, and access controls that they already apply to people and applications. Microsoft’s current Agent 365 guidance specifically ties agent governance to Entra for identity, Defender for security, and Purview for data governance.

And that makes this Copilot Studio migration more than a technical cleanup exercise.

Entra Agent ID gives an agent an enterprise identity. Agent 365 gives the enterprise a way to manage the agent population.

My recommendation

If your organization has been building Copilot Studio agents for some time, don’t treat this as simply an identity migration. With Entra Agent ID providing the identity foundation and platforms such as Agent 365 emerging to manage and govern agents at scale, this is a good opportunity to review your overall agent inventory, ownership, permissions, lifecycle, and governance model.

Ask:

• What agents do we have?
• Who owns each one?
• What can each agent access?
• Which agents are still being used?
• Which permissions are actually necessary?
• What happens when an agent or its owner is no longer needed?

These questions will become increasingly important as agent adoption expands.

The organizations that establish this discipline now will be in a much better position as the number, reach, and autonomy of their AI agents grows.

I am glad to see that

Agent identity is becoming a foundational part of enterprise AI governance.
