Compatibility of VCDA 4.7.3 with VMware Cloud Director 10.6.0.1

Ensuring compatibility between VMware Cloud Director Availability (VCDA) 4.7.3 and VCD 10.6.0.1 is critical for delivering a seamless disaster recovery service. In my experience, several compatibility-related issues can arise during deployment.

1. Unsupported API Calls:

Issue: Certain API calls fail due to mismatched versions of VCDA and VCD.

Scenario: A provider reported that scheduled DR workflows stopped working after upgrading VCD to 10.6.0.1.

Solution: Always refer to VMware’s Interoperability Matrix before upgrading either component. In this case, upgrading VCDA to 4.7.3 resolved the issue.

2. Recovery Workflow Errors:

Issue: Recovery workflows fail with errors related to VM registration.

Scenario: During a failover, the target site’s vCenter server displayed errors about insufficient resources.

Solution: Validate that the target site has adequate compute, storage, and network resources for the recovered workloads. Pre-provisioning resources can help avoid this issue.

3. Failback Challenges:

Issue: Failback operations fail to complete successfully.

Solution: Check the replication direction and ensure that all network and storage mappings are bidirectional. Additionally, verify that the failback policies in VCDA match those configured in VCD.
