Change the network and host of a virtual machine during vmotion is not supported on the "source" host (5.5u3 -> 6.5)

Hi,

I'm trying to vMotion VM's from a 5.5 U3 (Standard vSwitch) towards a 6.5 Host using dSwitch.

When performing this action I get the message: "Change the network and host of a virtual machine during vmotion is not supported on the "source" host"

AFAIK this should work from a 5.5 U3+ Host?

Although the message states that the source host is not supported I also tried making the destination dSwitch a version 5.1 and a 5.5 but this doesn't make a difference.

Am I overlooking something or is this simply not possible?

Thanks,

/K
