Migrate External PSC Deployment to Embedded PSC deployment Using Converge Tool

[#1]

Here is the brief description of how Convergence tool works.

Converge Tool can migrate an External Deployment PSC to an Embedded deployment PSC,  it also has the ability to decommission the external PSCs after the migration.

Note: Your vCenter components must be upgraded to 6.7 Update1 appliance.

Prerequisites

1.Disable VCHA if its enabled on 6.5.

2.Reduce\disable DRS automation level.

3.Take the VMware snapshots for all vCenter components, if possible go for VCSA backup also

4.remove the secondary nic if its assigned before the upgrade

Using Tool:

Step 1-VCSA 6.7 Update 1 ISO will have the vcsa-convergence-cli tool so mount the ISO any windows/Linux machine.

  

Here converge folder will have converge JSON file and decommission folder will have decommission JSON file.

Step 2- Expand the vcsa-converge-cli directory and go to templates. Open the converge directory and copy the converge.json file to your local machine.

Step 3 – open the converge JSON file in your fav editor and looks as below

 

Step 4 - Fill out the fields as below and save the file .

1. Information about the Managing vCenter or ESXi Host.
2. Information about the vCenter Server you wish to Converge to Embedded.
3. (Optional) Active Directory Information if you wish to join the Embedded vCenter to AD.
4. (Optional) please mention the other external PSC if you have .

  Step 5 :from CMD prompt run vcsa-converge-cli\win32>vcsa-util.exe converge –no-ssl-certificate –verbose C:location of your .json file and run

Step 6: VCSA converged to  embedded PSC successfully .

Verify the vCenter with Embedded platform service control from the VAMI page.

Note:   Before we head on to decommission please make sure there are no VCSA associated with external PCSs that you are going to decommission .

Decommissioning Steps:

Step 1: copy the decommission JSON file to the local machine and fill out the required field

1. fill Information about the Managing vCenter or ESXi Host of the External PSC.
2. Information about the Platform Services Controller you wish to Decommission.
3. Information about the Managing vCenter or ESXi Host of an Embedded vCenter in the SSO Domain.
4. Information about the Embedded vCenter in the SSO Domain.

Here is the screen shot reference .

Repeat the above steps for second PSC if you have.

This completes the VCSA convergence .
