Before installing or upgrading, check the software requirements, installation and upgrade prerequisites, and port settings in this topic. This information applies to all 2.0 releases.

The basic software requirements are as follows:

The minimum vCenter 5.5 version is vCenter 5.5u3. Subsequent updates to vCenter 5.5 are supported.

The minimum vCenter 6 version is vCenter 6.0u2. Subsequent updates to vSphere 6.0 are supported, but vSphere 6.5 is not supported.

The minimum ESXi version is 5.1.

vMotion (zero-downtime migration) requires virtual hardware version 9 on the VM.

If you intend to use cross-cloud vMotion, the same affinity restrictions apply across clouds as they do on-premises. See the EVC and CPU Compatibility FAQ.

The policy migration feature requires NSX 6.2.x or higher.

Before upgrading, you must open the ports you need, as listed in the VMware vCloud Air Hybrid Cloud Manager Installation and Administration Guide, and Hybrid Cloud Manager 2.0 Port Access Requirements.

As a convenience to users upgrading an installation, Hybrid Cloud Manager 2.0 Port Access Requirements lists port requirements that have been added since version 1.0. In Hybrid Cloud Manager 2.0 Port Access Requirements, H&N is an abbreviation for the Hybridity and Networking service virtual appliance. This virtual machine functions as the management appliance.

Note

Pay attention to the Purpose column. For example, if you are not going to configure vMotion, you do not need to open port 8000.

The release notes contain the most recent information on upgrading to version 2.0. The installation prerequisites and configuration instructions are available in the VMware vCloud Air Hybrid Cloud Manager Installation and Administration Guide. See the section titled, "Modifying or Uninstalling Hybrid Cloud Manager" for instructions on upgrading your legacy installation.

Note

Contact VMware Global Support Services (GSS) before starting an installation or an upgrade. If you share your configuration with Support, they can ensure that the vSphere and vCloud Air environments are compatible.

For example, to use cross-cloud vMotion, your vSphere NSX version and your vCloud Air Network Services Platform version must be compatible. If you share your configuration with Support, they can ensure that the vCloud Air environment is compatible before you start the upgrade or installation process.

The following practices support a successful upgrade.

Before attempting an upgrade, halt or reschedule any near-term migration processes (vR or vMotion).

After an upgrade, ensure that there are no active migration processes.

Redeploy your appliances one at a time.

You must redeploy a Cloud Gateway or Layer 2 Concentrator appliance before you can stretch a network using the upgraded appliance.

If an appliance was used for a stretched network before the upgrade, redeploy the appliance and wait to verify that the tunnel is restored and active.

Resume or reschedule your migrations, if necessary.
