Has anyone ever used frx.exe -migrate-vhd? I want to copy a profile disk (VHDX) to a new one with parameters

-src -dest -dynamic and -site-mbs

But nothing happens, although the command returns “Operation completed successfully!” If I do a typo like -des it also returns “Operation completed successfully!” This is really strange… frx command-line utility reference - FSLogix | Microsoft Learn

The only time I have used -migrate-vhd was when I wrote a script to migrate profiles from VHD to VHDX. I didn't use all the parameters you are using though. Was a while ago, but I don't recall seeing that behaviour. Haven't needed it for a while as I now always use VHDX by default. https://github.com/ScottKnights/FSLogix/blob/main/Convert-VHDToVHDX.ps1
