We have a current production infra vsphere 6.0 with old esxi & storage infra. We have build a new vsphere infra with vcenter 6.7, new esxi hardwares to 6.7 and storage array. There is no storage communication between the current & new infra. We are looking for the possibility of migration the virtual machines from the current to new infra which could be a cold/hot migration. Both the sites have different SSO domain hence ELM is not support. Kindy suggest the requirements
