cross-vCenter migration error

[AnonAdmin]

I'm attempting my first cross-vCenter migration but getting the following error;

PS C:\> $vm = Get-VM vmGuest -Server 'SourceVC'
PS C:\> $vm | Move-VM -Destination (Get-VMHost 'DestHost' -Server 'DestVC') -NetworkAdapter (Get-NetworkAdapter $vm -Server 'SourceVC') -PortGroup (Get-VDPortgroup -VDSwitch 'dvSwitch' -Name 'VLAN1') -Datastore (Get-Datastore 'DS01' -Server 'DestVC')

Move-VM : Move-VM Could not obtain the result of task '/VIServer=domain.com\admin@SourceVC:443/Task=Task-task-748415/'. Task name is 'RelocateVM_Task'. The following error occured:

Which PowerCLI version are you using?
And which PowerShell version?

Is there a reason why you did not use the Server parameter on the Portgroup parameter value?

Get-PowerCLIVersion is showing VMware PowerCLI 12.0.0 build 15947286 and $PSVersionTable is showing 5.1.14393.5127.

Good catch on the missing server parameter for my Portgroup - I added that in but still got the same error.

As the next step, I would suggest upgrading your PowerCLI version.

Which vSphere version is this running against?
Source and destination VCSA

It looks like an error reporting issue, but from "Cannot convert type 'VirtualMachineFeatureRequirement' to 'Object'." I would say that it's likely that the migration fails due to some hardware features that are required on the target host and are not matched. Are you migrating a powered on or powered off VM?

You are correct - after looking at the logs I learned that the version of the destination vDswitch is older than the source version.
