Convergence is the process of reconfiguring or converting a vCenter Server instance with an external Platform Services Controller to a vCenter Server instance with an embedded Platform Services Controller.

Convergence Internal Workflow illustrates the process of converging a single standalone vCenter Server with an external Platform Services Controller to a vCenter Server with an embedded Platform Services Controller.

Description

Stage 0

Stage 0 represents the original vCenter Server A with external Platform Services Controller A node.

Stage 1

In Stage 1, the vcsa-util converge utility performs the following tasks:

  1. Deploys the new embedded Platform Services Controller B on the vCenter Server A and sets it up so that that all the data in the original Platform Services Controller A is replicated in the new embedded Platform Services Controller B.

  2. Configures the new embedded Platform Services Controller B so that it works on the vCenter Server A node.

  3. Repoints vCenter Server A to the new embedded Platform Services Controller B.

Stage 2

Stage 2 shows the new node which contains vCenter Server A with embedded Platform Services Controller B.

The original Platform Services Controller A can be decommissioned.
