To combine the resources of two provider VDCs, you can merge these provider VDCs into a single provider VDC.

Starting with VMware Cloud Director 10.4, you can merge provider VDCs that are backed by NSX-T Data Center.

Also starting with version 10.4, VMware Cloud Director supports merging provider VDCs that are not backed by networking resources, as well as merging a provider VDC that is not backed by networking resources with an NSX-backed provider VDC.

Prerequisites

  • Verify that both provider VDCs have the same enabled state.
  • If you want to merge provider VDCs that are backed by NSX-T Data Center, verify that both provider VDCs are backed by the same NSX-T Manager instance and by the same Geneve network pool.
  • Verify that both provider VDCs are backed by the same vCenter Server instance and by the same data center.
  • Verify that the provider VDC that you want to expand supports the highest hardware version used in the provider VDC that is to be merged. If the merging provider VDC contains a VM with a higher hardware version than the highest one supported by the expanding provider VDC, the merge fails.
  • Verify that both provider VDCs contain only elastic organization VDCs.
  • If you want to merge provider VDCs with network pools that are backed by VXLAN, verify that the VXLAN pools have the same NSX working state. See "Verify the NSX Working State" in the NSX Upgrade Guide.
