How to move vCenter Server to another Datacenter

  • make a clone of the vCenter VM, export it and import into the target Datacenter storage
  • edit the properties of the new VM so it’s MAC address is the same as the old VM (only if using DHCP)
  • shutdown vCenter from web interface
  • with vSphere client connected to the source host, shutdown the Guest OS of the old VM
  • with vSphere client connected to the destination host, register and power-up the new VM
