Cross hypervisor instant vm recovery

[Friday2]

Now with Veeam10 it's possible to do cross hypervisor instant VMrecoveries. So i was thinking about automating part of the migration process from Hyper-V to VMware for us.

I've got this snippet so far. But it reports error

Code: Select all

Add-PSSnapin VeeamPSSnapin

$servers = Get-VBRServer | Where-Object { $_.Type -match "ESXi" -and $_.Name -match "172.21.41." }

$ctr = 0
foreach ($vm in Get-VBRJob -Name "migrationjob" | Select-Object @{Name="vms"; Expression={ $_.GetObjectsInJob().name }} | Select-Object -ExpandProperty "vms") {
    while ($ctr -ge $servers.Count) {
        $ctr -= $servers.Count
    }

    $restorepoint = Get-VBRBackup -Name "migrationjob" | Get-VBRRestorePoint | Where-Object { $_.Name -eq $vm } | Sort-Object -Property CreationTimeUtc -Descending | Select-Object -First 1
    $restorepoint
    Start-VBRInstantRecovery - -RestorePoint $restorepoint -Server $servers[$ctr] -PowerUp 
    start-vbr

    $ctr++
}

Code: Select all

So the scripts gets all vms in a job, loops them, gets the latest restorepoint for each of them, then it should start an instant vm recovery (We're "load balancing" servers across all hosts available in the cluster as well), this is where it fails with the error that Hyper-V isn't a supported platform (Which it wasn't until Veeam 10 if i understand correctly).

I've looked through all cmdlets containing "instant" but it seems like there's no "specialized" version for doing Hyper-V to VMware in here as of now.

Thoughts on how this could be achieved? We're on Veeam 10.0.0.4461

Hello,
I did not test, but in the list you mention, there is Start-VBRViComputerInstantRecovery... and the user guide says for that cmdlet https://helpcenter.veeam.com/docs/backu ... ml?ver=100

Hyper-V workloads to restore them to VMware vSphere VMs.

Does that work?

Best regards,
Hannes

This seems to do the job indeed, if i knew relations between objects better i could probably have shaved it a bit, but it works.

Thanks Hannes!

Hi @Friday2,

Check out Powershell Cookbook module and Show-Object cmdlet specifically. It'll help you to sneak under each object's declared properties/methods and understand relations between classes better. For example:

Code: Select all

Get-VBRJob | Show-Object

We use it quite often and it does save us some time.

Thanks,
Oleg
