Parallel or sequential cluster-level upgrades

NSX components within a Cloud Foundation deployment can also be upgraded in a variety of ways to best utilize and minimize maintenance windows. 

​NSX components within a Cloud Foundation deployment can also be upgraded in a variety of ways to best utilize and minimize maintenance windows.  Clusters can be upgraded sequentially (one after another) or multiple* in parallel. The Administrator has the option to choose some clusters without having to choose all of them.

​

​The NSX upgrade process will upgrade all NSX components within the NSX fabric instance which can span multiple workload domains. 

The NSX fabric updates are applied by firstly upgrading the NSX Upgrade Co-ordinator.

​

The NSX Edge clusters are upgraded next, and need be updated before the host clusters.

Then we upgrade the host clusters.

And lastly, the NSX Manager cluster are the final components to be upgraded in this sequence.

Notes:

This feature is not applicable to the management domain.  The management domain is deployed from Bring-up and utilizes vLCM baselines and cannot be configured with vLCM images.

*The VMware Cloud Foundation 5.0 release will support upgrades/patching of up to 5 clusters in parallel (at the same time).
