Re: Migrate VR and SVM to other cluster


Both ways work Makrand - but I suggest you use the "restart with cleanup" option. In 4.11 you will also find this option does a parallel startup / shutdown of old/new VR, leading to less VR downtime.

    Hi Dag,
    
    For VRs do destroy works in same fashion as of system VMs or just doing
    clean network restart is only option for spinning new VR?
