Azure Migrate appliance download SHA256 hash does not match portal-published value

Question

Azure Migrate appliance download SHA256 hash does not match portal-published value

Admin-Avila, Dom 0

We are deploying an Azure Migrate appliance for VMware discovery.

The appliance package downloaded from the Azure portal fails SHA256 integrity validation. The SHA256 value calculated locally does not match the SHA256 value currently published in the Azure portal for that same appliance download.

We have already:

Deleted the original package
Downloaded a fresh copy from the Azure portal
Recalculated the SHA256 hash with PowerShell
Confirmed we are validating the downloaded file shown by the Azure Migrate project

This blocks appliance deployment before installation and registration.

Can a Microsoft engineer confirm whether the published SHA256 value for the current Azure Migrate appliance package is correct, or whether there is a known issue with the appliance download/CDN distribution?

I can provide the expected and calculated hashes privately if needed.

Hi @Admin-Avila, Dom

Thank you for sharing the details. We understand that you are deploying the Azure Migrate appliance for VMware discovery, but the appliance package cannot pass SHA256 integrity validation because the locally calculated SHA256 value does not match the SHA256 value currently shown in the Azure portal.

Confirm you are comparing the hash against the correct artifact: -

The Azure offers different appliance artifacts depending on the deployment method and each one has its own SHA256 value. A common cause of mismatch is comparing the hash of one artifact against the published value for a different one. Please confirm which artifact you downloaded

Rule out a partial/interrupted download: -

Even though you have already re-downloaded once on a large package silent download interruptions are a common cause of repeated hash mismatches. Please:

Verify the file size on disk matches what the portal shows.

Try downloading from a different browser (or a different machine/network) to rule out a proxy/CDN edge cache issue.

If you use any download manager, web proxy, AV scanner, or DLP solution that streams/inspects the file, try a download path that bypasses it temporarily.

Avoid extracting/repackaging before hashing hash the file exactly as downloaded.

The documentation recommends CertUtil for hash validation. Both should produce the same value. If you previously used a different tool or piped output, please use the commands below to remove any tool related variability.

Command Prompt: CertUtil -HashFile "C:\Path\To\MicrosoftAzureMigration.ova" SHA256
PowerShell: Get-FileHash -Path "C:\Path\To\MicrosoftAzureMigration.ova" -Algorithm SHA256

After you have completed the steps above, if the hash still does not match the value published for the correct artifact, please send us the details below in a private message so we can look into it further.

Azure Migrate project name and region

Artifact type (OVA / VHD / ZIP) and file name

File size on disk vs. expected size

Are you experiencing this issue on multiple machines or just one

SHA256 value shown in the portal at download time

SHA256 value calculated locally (include the exact command used)

When the hashes don't match, do you get a particular error message

Download timestamp (with time zone) and the browser used

Whether the same mismatch reproduces from a different machine/network

It really seems as though the documentation is out of data. I do not have the ability to create a ticket no matter what I do, I am circled back to post on the QA again. I am hoping someone from Microsoft can actually either get me updated documentation, or get me a ticket opened, as for what ever reason, I can create one myself.

Hi @Admin-Avila, Dom , Apologies for the inconvenience. I have already sent you a private message with a link to help you open a support ticket. Please let me know if you encounter any errors while opening the case. I also requested a few other details please help me with those and we can schedule a meeting to discuss this further.

i Admin-Avila, Dom,

Thx for sharing urs issue here at Q&A portal. If a fresh download from Azure portal still doesn’t match the SHA256 shown for that same Azure Migrate appliance package, don’t install it. Hash mismatch should be treated as a failed integrity check, even if it may just be a portal/CDN metadata mismatch. I’d retry once from a different network/browser and make sure the file isn’t being altered by proxy/AV inspection. If the hash still differs, this needs Microsoft confirmation.

Use PowerShell something like

Get-FileHash .\AzureMigrateAppliance.zip -Algorithm SHA256

Docs if u would like https://learn.microsoft.com/en-us/azure/migrate/tutorial-discover-vmware & https://learn.microsoft.com/en-us/azure/migrate/migrate-appliance

Open an Azure Migrate support case and provide the project region, appliance type, download time in UTC, portal-published hash, calculated hash, file size, and download URL if visible. Ask MS to confirm whether the published SHA256 or the current CDN package is wrong.

Rgds,

Alex
