I found this KB 2004578 and thought that of course should this be done with PowerCLI
I made a function to be able to do it just by sending the VM parameter, it can be done if the VM is already shutdown with a simple one-liner
1Get-VM v2vtest2 | Get-ScsiController | where {$_.Type -eq "Paravirtual"} | Set-ScsiController -Type VirtualLsiLogicSAS
But I wanted a more sophistical approach where my function shutdown the VM properly and then change the controller and starts the VM, the tricky part here was to check that the VM actually had shutdown before I change controller
01function Change-ScsiController{
04Stop a VM and replace the SCSI controller and start it again
07Use this function to change scsi cntroller
