Migrate fslogix data from local AD to Entra ID Domain services

Jim Huang (RD-CN) 0

Hello,

We have used AVD for 3 years. We have many data in FSlogix.

Current, we are migrating our VMs in AVD from local AD to Entra ID Domain.

We found the SID of same user is different between AD and Entra ID.

We first login VM in Entra ID Domain. This will create one SID folder.

Then we tried to copy old VHD file into new SID folder.

We found the new VM can't mount fslogix.

I want to know if we can migrate data to new fslogix.

Thanks.

Best Regards,

Jim

Hello @Jim Huang (RD-CN)

Thanks for reaching out on Microsoft learn Q&A for your query.

From the AVD side, we don't have a support method to Migrate fslogix data from local AD to Entra ID Domain services. I’m curious to know why do you move to Entra ID domain services? It comes with limitations. It doesn’t support many features like SSO or Intune Management.

In the past, VMs joined the domain. The domain is local AD.
Current, we are joining VMs to Entra ID(AAD).

We can use SSO and Intune to manage our VMs.

Hi @Jim Huang (RD-CN)

Thanks for getting back with the details. So, this isn’t Entra ID Domain Services. It is just Entra ID. The names are confusing, but it’s important to differentiate.
The same applies, there is no migration for the FSlogix disks itself. I assume you keep hybrid identities? (don’t confuse it with hybrid join of the VMs). You can use OneDrive known folder move to bring over the user data and start with new profiles on the be host pools.

This is not a good suggestion. I hope to help users migrate in batches, not let users use OneDrive to migrate by themselves.

Hello Jim Huang (RD-CN) Do the users use OD to store their data? In that case, there is no manual intervention needed by the user. Did they try the approach?

What is OD? We use Azure Storage file share for FSlogix.

Hello Jim Huang (RD-CN)

I was waiting to hear from you to understand if you have made in progress with this. Migrating FSLogix data from a local Active Directory (AD) to Microsoft Entra ID Domain Services can be challenging due to the differences in Security Identifiers (SIDs) between the two environments. When a user logs into a VM that is joined to Microsoft Entra ID, a new SID is generated, which means that the existing FSLogix profile data associated with the old SID will not be accessible.

Unfortunately, FSLogix does not provide a direct migration path for user profile data from traditional AD to Entra ID. The profiles are tied to the specific SIDs, and as you have discovered, simply copying the VHD file to the new SID folder will not work because the new VM cannot mount the FSLogix profile.

As I suggested earlier, to manage this situation, you may consider implementing a solution like OneDrive with known folder move, which allows users to save their data outside of their profile. For smaller use cases, you can use the frx command-line utility to help copy local profiles into a new VHD(x), but this would still require some manual intervention to ensure that the data is correctly associated with the new SID.
