Expand the different sections of the wizard and change the configurations as necessary.

For information about which configuration options you can change, see Which Options Can I Reconfigure? below.

For the options that you can modify, refer to Deploy Tanzu Kubernetes Grid Integrated Edition by Using the Configuration Wizard for instructions about how to fill in each section.
When you have finished reconfiguring, click Generate Configuration.
Optionally export the PksConfiguration.yaml file to save a copy of your configuration.
Click Apply Configuration and Continue to complete the reconfiguration of Tanzu Kubernetes Grid Integrated Edition.

Reconfigure Your Tanzu Kubernetes Grid Integrated Edition Deployment by Importing a YAML File

The procedure to reconfigure Tanzu Kubernetes Grid Integrated Edition deployments by importing an updated YAML file is as follows.

Expand Configuration and go to the TKGI Configuration view of the management console.
Select Wizard to be taken to the configuration wizard for Tanzu Kubernetes Grid Integrated Edition.
Scroll to the bottom of the screen and click Import YAML.
Drag the YAML file into the Import Configuration File window, or click Browse to navigate to it.
In the Configuration File editor, modify the contents of the YAML file appropriately for the new instance of Tanzu Kubernetes Grid Integrated Edition that you want to deploy.

For information about which configuration options you can change, see Which Options Can I Reconfigure? below.

If the YAML was generated by an instance of the management console that is running in a different vSphere environment, update the passwords for NSX Manager, vCenter Server, and Harbor. For more information see Deploy Tanzu Kubernetes Grid Integrated Edition by Importing a YAML Configuration File.

To abandon this YAML and start again, click Import to upload the YAML again or to import a new one.

You can also click the Edit in Wizard button, to open the imported configuration in the wizard.
Click Apply Configuration and Continue to complete the reconfiguration of Tanzu Kubernetes Grid Integrated Edition.

* If you update the NSX Manager CA Cert field, TKGI MC will update BOSH and TKGI to the new NSX-T CA certificate. For clusters that you have already created, you must update those clusters to use the new certificate. You must manually update the NSX-T CA certificate for the related NCP configurations.
** If you previously used a local user database and change to AD/LDAP or SAML, the local user database is deleted.
