Cloud sites management includes establishing and re-establishing trust between sites. After you initiate pairing from the local site and complete the pairing from the remote site, VMware Cloud Director Availability establishes a trust between the two cloud sites. Re-establish the trust after upgrading VMware Cloud Director Availability, after replacing the Cloud Service certificate, or after registering additional Replicator Service instances.
VMware Cloud Director Availability to VMware Cloud Director Availability Interoperability
You can pair sites that have different VMware Cloud Director Availability versions deployed. For example, you can pair a cloud site where version 4.0 is deployed with an on-premises site where version 3.5 is deployed. You can also pair with a cloud site where version 3.5 is deployed. This scenario can occur when upgrading the sites one at a time or to migrate workloads from an earlier vSphere and VMware Cloud Director versions to a site with current vSphere and VMware Cloud Director versions.
Before pairing VMware Cloud Director Availability sites, verify the interoperability of the versions of VMware Cloud Director Availability between the source site and the destination site in the following tables:
| VMware Cloud Director Availability On-Premises Appliance | Cloud Site 3.0 |
Cloud Site 3.5 |
Cloud Site 4.0 |
|---|---|---|---|
| 3.0 | Supported | Supported | Supported |
| 3.5 | Supported | Supported | Supported |
| 4.0 | Supported | Supported | Supported |
| Source Cloud Site VMware Cloud Director Availability |
Destination Cloud Site 3.0 |
Destination Cloud Site 3.5 |
Destination Cloud Site 4.0 |
|---|---|---|---|
| 3.0 | Supported | Supported | Supported |
| 3.5 | Supported | Supported | Supported |
| 4.0 | Supported | Supported | Supported |
- For version 3.0, the site must be running version 3.0.5 or if later is available.
- For version 3.5, the site must be running version 3.5.2 or if later is available.
Migration from Earlier VMware Cloud Director Availability Versions
By pairing an earlier and the latest VMware Cloud Director Availability versions, you can migrate workloads from source sites where the latest VMware Cloud Director Availability version does not support either the version of vCenter Server or VMware Cloud Director.
VMware Cloud Director Availability is fully capable of migrating workloads running on earlier vSphere and VMware Cloud Director versions that are near or are already EOS. If there is a VMware Cloud Director Availability version compatible with the vSphere and the VMware Cloud Director versions in the source site, you can pair it to VMware Cloud Director Availability 4.0 deployed in a cloud site with the latest vSphere and VMware Cloud Director versions. For example, see the following table:
| Source Site VMware Cloud Director Availability |
Destination Site VMware Cloud Director Availability |
|---|---|
| On-premises site A, deployed version 3.5 with vSphere 5.5 or later. | Cloud site B, VMware Cloud Director Availability 4.0 with a supported VMware Cloud Director version*. |
| Cloud site X, deployed version 3.0 with vCloud Director 8.2, 9.0 or 9.1. | |
| Cloud site Y, deployed version 3.5 with vCloud Director 9.0 or 9.1. |
- In an on-premises site with vSphere 5.5, deploy an on-premises appliance version 3.5 and pair it to VMware Cloud Director Availability 4.0 deployed in a cloud site with a supported VMware Cloud Director version*. You can then migrate all virtual machines to the later cloud site.
- In a cloud site with vCloud Director 9.0, deploy version 3.0 and pair it to VMware Cloud Director Availability 4.0 deployed in a cloud site with a supported VMware Cloud Director version*. You can then migrate all vApps to the later VMware Cloud Director site.
