Linux 5.10.0-21-cloud-amd64 #1 SMP Debian 5.10.162-1 (2023-01-21) x86_64

This version of Linux is in AWS in the Instance EC2 after migrating from Azure to AWS with Elastic Disaster Recovery.

Now I want to migrate from AWS to Azure using the Azure Migrate following the steps in the following article in the section Installation guide for Windows AWS VMs, step #2.

This the procedure in Linux.

I have the next error ASRMobilityServiceBootDiskNotFound in file InstallerErrors.json

And this the error in the file ua_install.log.


Does anyone know why this problem could occur with Azure migrate?

    Hello Mike,

    Good day!

    If the boot and root partitions are on different disks, the configuration is not supported by ASR. It most likely to result in this error "ASRMobilityServiceBootDiskNotFound" If this is not the reason, one of the below could be possibly blocking you from installing ASR agent.

    Other configurations that aren't supported with ASR are

    • /boot on LVM not supported
    • These directories (if set up as separate partitions/file-systems) must be on the same OS disk on the source server: /(root), /boot, /usr, /usr/local, /var, /etc.
    • Multiple OS disks aren't supported.

    This is documented on ASR Support Matrix, for details see,

    I also met this error.

    And here is the my situation.

    My source VM is the Instance EC2 in AWS. I want to migrate it to Azure.

    Here is the information about source VM, what else I can do for now?
