Connecting different TAP versions in a multicluster configuration is not supported

Products

• VMware Tanzu Platform

Issue/Introduction

Installing Tanzu Application Platform (commonly known as TAP) in various topologies to reflect your existing landscape. VMware has tested and recommends a multicluster topology for production use. Because flexibility and choice are core to Tanzu Application Platform’s design, none of the implementation recommendations are set in stone.

The multicluster topology uses Tanzu Application Platform profiles. Each cluster adopts one of following multicluster-aligned profiles:

• Iterate: Intended for inner-loop iterative application development.
• Build: Transforms source revisions to workload revisions; specifically, hosting workloads and supply chains.
• Run: Transforms workload revisions to running pods; specifically, hosting deliveries and deliverables.
• View: For applications related to centralized developer experiences; specifically, Tanzu Developer Portal and metadata store.

The caveat is that all clusters need to run same TAP version. 

Resolution

It's not supported (and not recommended) running different TAP version with multicluster topology.
