Is This Possible to update Os Profile after Vm migration? Or Can I install provisionVMAgent in virtual machine after migration of VM?

Answer 1

You could see provisionVMAgent working at the VM provision time from this , So it's not possible to update it after VM has created.

In this case, when you have created a custom-image VM from an unmanaged generalized os image , you could manually install the Windows VM Agent . The VM Agent is supported on Windows Server 2008 R2 and later.

The VM Agent can be installed by double-clicking the Windows installer file. For an automated or unattended installation of the VM agent, run the following command:

msiexec.exe /i WindowsAzureVmAgent.2.7.1198.778.rd_art_stable.160617-1120.fre /quiet

Hope this could help you.
