This Changelog is updated with each release of the product or when necessary.

These tables provide the update history of VMware Cloud Director Availability for each version.


Table 1. VMware Cloud Director Availability 4.5 | Build 20795276 (Product version:
Release Description Additional Resources
24 NOV 2022 vSphere DR and migration between vCenter Server sites:
Enhancements in DR and migration to vSphere: the on-premises appliance no longer requires public URL and supports a single-step pairing to the provider site. The pairing from on-premises to a provider no longer requires additional steps for confirming the pairing from the provider site. However, the pairing between two provider sites remains a two-step process, initiated from one provider site, then completed from the other provider site.
Add Replicator appliances in the provider site: in the provider-hosted vCenter Server instance, after configuring the vCenter Replication Management Appliance, you can add one or more Replicator Appliance instances. That scales the performance when replicating tenant vSphere workloads between an on-premises vCenter Server instance and a provider-hosted vCenter Server instance or between provider-hosted vCenter Server instances. Adding Replicator Appliance instances is also supported for existing environments.

The vCenter Lookup Service address entered in the vCenter Replication Management Appliance also applies the same address in all registered and online Replicator Appliance instances without having to manually enter it for each instance.

Recovery settings for vSphere DR and migration: you can preconfigure the destination virtual machines location and compute resource and the network mapping that apply when recovering the workload in the destination site.
View-only vSphere user: VMware Cloud Director Availability supports read-only users and allows users to only monitor replications or administrators to only monitor the system health and the replications. N/A
Replicate encrypted virtual machines: VMware Cloud Director Availability supports replicating virtual machines with an encryption-enabled storage policy, providing end-to-end encryption also in the case for vSphere DR and migration. For more information, see the Prerequisites.
Replications with cloud sites backed by VMware Cloud Director:
Extended control and management of replication policies: cloud to on-premises migrations can be disallowed separately from cloud to cloud migrations. Once the cloud site is upgraded to version 4.5, disallowing migrations to on-premises stops all outgoing migrations to all on-premises appliances in the organization, regardless of their VMware Cloud Director Availability versions.
System-wide notifications to peer sites: these advisories notifications can appear on the top of the VMware Cloud Director Availability pages after creating them in VMware Cloud Director. You can select a priority and duration for showing the message and its audience: to the administrator users, to users within a specific organization, or to the users in all organizations.
VM sizing policy selection: when creating or modifying a replication you can also select a VM sizing policy in addition to the VM placement policy. Within an organization, the VDC compute policies control the compute resources allocation for the recovered workload to several predefined sizes.
View-only system user: VMware Cloud Director Availability supports read-only users and allows users that are not an Organization Administrator to manage replications.
Advanced recovery settings: you can modify the destination network settings, the guest customization, and the guest customization script that are applied when recovering the workload in the destination site.
Clone a replication policy: you can duplicate each selected replication policy by clicking the Clone button.
Replications with any site:
Backup and restore automation: you can schedule the creation and the upload of the VMware Cloud Director Availability appliance backup files to an external server using Secure File Transfer Protocol (SFTP).
Service and appliance uptime: you can check the uptime of both the services and the appliance on the System Health page. Blog post
Recent Tasks: by expanding this global taskbar on the bottom of the page in the appliances interface, you can see both the system and the replication tasks that recently executed. To filter these tasks by exit criteria, click Running, Failed, or Succeeded. N/A


Table 2. VMware Cloud Director Availability 4.4 | Build 19925810 (Product version:
Release Description Additional Resources
23 JUN 2022

VMware Cloud Director Availability 4.4 and later can replicate tenant vSphere workloads between an on-premises vCenter Server instance and a provider-hosted vCenter Server instance or between provider-hosted vCenter Server instances. These setups require a new deployment topology. For information about deploying and pairing the new appliances, see the Installation and Configuration Guide in On-Premises and Provider Site document.

One-click migration: you can create a fast migration with a single click, skipping the advanced replication settings configuration.

Migrating vApp templates: when migrating vApp templates between cloud sites backed by VMware Cloud Director, you can migrate the vApp networks with their connectivity and migrate the statuses of "General > Gold_Master" and of Customize VM settings.

Network extension to VMware Cloud on AWS: you can stretch an L2 network to an SDDC in the VMware Cloud on AWS, by using the procedures for stretching an L2 network in the cloud. For information about the required additional Organization Administrator role rights for Organization vDC Gateway: View L2 VPN and Configure L2 VPN in VMware Cloud Director service, see Users roles rights in the Security Guide document. Blog post
Recovery plans execution reports: you can view live step execution progress and see a detailed HTML report for the recovery plan execution that contains replication details and the result of each plan step execution.
RPO compliance: the providers can generate and export Recovery Point Objective (RPO) compliance reports, grouped on an organization level, listing any RPO violations of the protections replicating during a specified period. The reports show whether, in the given period, any protection to the site and from it to on-premises sites meets or violates its RPO. The currently generated report can be viewed either in the interface, or in an HTML format and optionally exported as a TSV file.
Managed service replication assignment: you can select the tenant organization as a default owner for new replications or leave the system administrator as a default owner.
Remote site compatibility pre-upgrade check: when upgrading the cloud site, in the Update wizard, you can see which paired on-premises appliances are incompatible with the upgrade version. After upgrading, in the Peer Sites page you can also filter them by compatibility status.
Replication alignment with the destination storage profile: when creating new replications the disk type is provisioned depending on whether the storage policy allows thin provisioning in the Cloud Director organization VDC. After creating a replication, the disk provisioning type never changes.
Cloud collection of support bundles: you can allow log collection from the On-Premises to Cloud Director Replication Appliance during the initial configuration and pairing of the appliance and during re-pairing with a Cloud Director site. To simplify troubleshooting, activate log collection from the cloud, allowing the providers to easily obtain new on-premises support bundles.
Endpoints resource capacity filter: VMware Cloud Director Availability shows the destination required resources of the replications provisioned on a failover. For information about monitoring the required resources, see: Monitor the required resources as a tenant and Monitor the required resources as a provider.
On the Dashboard page or in the top navigation bar, you can directly submit product feedback by clicking Feedback.

Table 4. VMware Cloud Director Availability 4.3 | Build 18930473 (Product version:
Release Description Additional Resources
23 NOV 2021

Select endpoint address for each network adapter: in a Replicator Appliance instance or in a Tunnel Appliance with multiple network interfaces, you can specify which of the network adapters to use for local site communication.

Blog post
Tunnel connectivity: the following new sections are available for verifying the statuses of the connections from the local Tunnel Service to the following destinations:
  • Local components connectivity to all the remaining services on the cloud appliances in the local cloud site.
  • Remote cloud sites connectivity to the remote Tunnel Service instances in all paired remote cloud sites with the local cloud site.
  • On-Prem Incoming connectivity to all paired on-premises appliances with the local cloud site.


Replacing the Cloud Service certificate without impacting paired on-premises: the paired on-premises appliances verify the entire SSL certificate chain of the Cloud Service. As a result, when replacing the certificate with a valid CA-signed certificate, the paired on-premises appliances do not need re-pairing with the cloud site. Blog post
Multisite cloud to cloud authentication: when multiple Availability cloud sites use a single VMware Cloud Director instance you can use multisite authentication for performing regular replication operations when prompted to extend the session from Availability site A to Availability site B. Blog post

The providers can set more than one rule for retention of the instances. Up to five different retention rules can store instances with a granularity that is changing over time.

For example, the following four retention rules keep a total of 24 rotated instances.

  • 10 instances, over distance 10 minutes unit - Retention period: 100 minutes.
  • 10 instances, over distance 1 hours unit - Retention period: 10 hours.
  • 2 instances, over distance 3 days unit - Retention period: 6 days.
  • 2 instances, over distance 2 months unit - Retention period: 4 months.
Add virtual machines in existing vApp groups: you can group one or several new virtual machines to an already existing vApp replication from an on-premises site to the cloud site. Blog post
DR and migration plans: orchestrate and schedule the recovery and the migration operations across multiple virtual machines and vApps by using plans with sequences of delayable and pausable steps, containing execution settings and existing virtual machines and vApps replications references.
You can set the shortest RPO as 1 minute by using the slider for RPO. To meet shorter RPO, verify that you follow the recommendations for lowering the RPO violations occurrence and see the Replication Flow document. An I/O intensive workload protected with shorter RPO can cause RPO violations.

Storage reporting: VMware Cloud Director Availability shows the disk space used by each virtual machine replication and aggregates the disk usage information per organization. You can monitor the disk usage for every replication in all directions. You can also monitor the disk usage for every organization.

YouTube video

For tenant onboarding, storage, network, and usage reporting: VMware Cloud Director Availability provides public APIs that help to onboard tenants, and see the storage usage, the network settings, and the compute resource usage of the replications. For more information, on the documentation landing page see the API guide for your version under Other resources. N/A
Event notifications: you can monitor the event notifications that VMware Cloud Director Availability generates either by using a syslog server or in Cloud Director by monitoring the VMware Cloud Director Availability events.
SLA profiles: you can define and control the following Service Level Agreement (SLA) replications settings: Recovery Point Objective (RPO), retention policy for the point-in-time instances, quiescing, compression, and initial synchronization time by using SLA profiles that can be assigned to organizations.

YouTube video

Bandwidth throttling: you can configure a limit for the replication data traffic from the on-premises to cloud sites. You can also set a global limit for the total incoming replication traffic from all cloud sites. N/A
In the source site with vCenter Server 7.0 and ESXi 7.0, when resizing the disk of the source virtual machine, VMware Cloud Director Availability automatically resizes the protected virtual machine disk in the destination site, running any supported vSphere version. The existing replication instances are retained. Failover and Test Failover are supported from any instance, before and after the disk resizing. Until the replication instances before the resizing expire, the replica files continue to take the additional storage space. To save storage space, you can remove the old replication instances or change the retention policy.
Stored instances: to restore a workload to a previous state, you can use point-in-time or stored instances. To avoid the automatic retention of point-in-time instances, you can store particular point-in-time instances. The stored instances do not change and you can use them to recover the workload to the stored instance, regardless of the overall retention period of the point-in-time instances.

14 NOV 2019 Grouping VMs in a replication: for on-premises to cloud replications, multiple virtual machines can be grouped and managed as a single unit, to specify boot order and boot delay settings. N/A
  • Using replications: in the Tenant Portal or in the vSphere Client Plug-In, you can protect or migrate workloads by replicating vApps or virtual machines.

  • Create a migration: migrate a vApp or a virtual machine to a remote organization, and run the workload in the destination site, by configuring a migration. After a successful replication in the destination site, you can power on the source virtual machine in the destination site.

  • Create a protection: protect a vApp or a virtual machine from one organization to another, and keep the workload running in the source site, by configuring a protection. If the source site is unavailable, after a successful replication you can fail over and power on the source virtual machine in the destination site.

  • Performing test failover, failover, and reverse: protect or migrate workloads by replicating vApps or virtual machines. Then, from or to on-premises sites you can test a failover, fail over, and reverse failover workloads to or from cloud sites.

  • Evacuate the replication data from a datastore: to perform maintenance operations on a local datastore in the cloud site, you must first remove all incoming replications and replication data placed on that datastore. To evacuate the replications from the datastore at once, you apply an alternative storage policy to all incoming replications on the datastore.
  • Replicator Service maintenance mode: to prepare a Replicator Service instance for maintenance without disrupting replications, you can evacuate the incoming replications from the Replicator Service instance to other local Replicator Service instances in the cloud site.
  • Rebalance replications: to distribute the incoming replications evenly over all Replicator instances in the site, you can rebalance the replications.
  • Monitor tenant traffic: as a tenant, you can see a traffic data chart for your organization. The chart shows the bytes of transferred data for the last five hours, up to two months.
