Hello Diana Piloya,

Thank you for reaching out to the Microsoft Q&A forum.

Here are a few steps you can follow to troubleshoot and resolve this:

Check for Prerequisites:

Ensure that all prerequisites for the update are met. Check for compatibility with the current OS and configuration. Also, verify if there are any dependencies (e.g., specific versions of other software) that need to be updated first.

Agent Logs:

Review the agent logs to get more detailed error messages. These logs are usually stored in C:\ProgramData\Microsoft\Azure\AzureMigrate\Logs. Look for any issues related to the update process.

Manual Update:

If the automatic update is failing, you can attempt a manual update:

Download the latest version of the Azure Mobility Service agent from the official Microsoft download page.

Run the installer and select the update option. This should overwrite the current version with the latest one.

Uninstall and Reinstall:

If the update is still not working, you can uninstall the current agent and reinstall the latest version:

Use Add or Remove Programs (or Programs and Features) to uninstall the "Microsoft Azure Mobility Service".

Then, reinstall the latest version using the manual method above.

Check Windows Firewall and Security Settings:

Sometimes, firewall or security software can block the update. Ensure that the necessary ports and domains (as outlined in Azure's documentation) are not blocked by any firewall or antivirus software.

Ensure Sufficient Disk Space:

Make sure that the server has enough available disk space for the update to complete.

Run as Administrator:

Make sure to run the update process as an Administrator to avoid permission issues.

Let me know if you have any questions?

Hello Diana Piloya,

To Update Mobility service manually on each protected server:

Before you start, ensure that the configuration server, scale-out process servers, and any master target servers that are part of your deployment are updated before you update the Mobility Service on protected machines.
Locate the agent installer based on the operating system of the server.

If you're replicating Azure IaaS VMs from one Azure region to another, don't use this method. For information about all available options, see our guidance.

Copy the installation file to the protected machine, and run it to update the Mobility Service.

Please refer below document for more details:

https://learn.microsoft.com/en-us/azure/site-recovery/vmware-physical-manage-mobility-service#update-mobility-service-through-powershell-script-on-windows-server

If the installer is not present on the appliance, Microsoft provides official Mobility Agent binaries here: https://github.com/Azure/Azure-SiteRecovery/blob/main/MobilityAgent/OnPremiseToAzure/AgentDownloadLinks.md

Could you please check it and let us know if it is helpfull?

Thanks,
Suchitra.
