Hi, I am having vCenter Server 5.5 along with vSphere 5.5 and I am now planing to upgrade to vCenter 6. Can I deploy one more vCenter Server 6 along with vCS 5.5 that already exist? I would to do this because my existing vCS 5.5 has RAM only 4GB and I cannot upgrade to 8 since I cannot edit this machine any longer. After upgrade upgrading the vCS to 6 or having new vCS 6 along with vCS 5.5 I would then upgrade my vSphere host from 5.5 to 6 using integrated VUM. Is this doable?
