VMware VCSA 6.0 to 6.5 upgrade: deploy VCSA – pt.1

vcsa60to65upgdeployvcsa01

VMware introduced in vSphere 6.5 the upgrade tool that allows the upgrade of an existing VCSA to version 6.5 with a simple procedure.

The upgrade procedure can be applied to vCenter Server version 5.5 or 6.0 and Platform Services Controller Appliance 6.0. Two stages are involved during the upgrade process:

  • deployment of the new VCSA
  • copy of the configuration from source vCenter Server

Keep in mind that the upgrade process doesn’t delete the old vCenter Server and its configuration but simply copies data to the new VCSA and then powers the source vCenter off. This allows to quickly restore the old vCenter Server if the upgrade process fails.

Prepare the environment

To perform a successful upgrade, there are two main prerequisites that must be met:

  • The cluster where the source VCSA resides has the DRS not set to Fully Automated
  • If the VCSA uses an external Update Manager you need to run the Migration Assistant

 

Disable Fully Automated DRS

During the upgrade process, the cluster where the ESXi host that manages the source vCenter Server resides must be configured to have the DRS not set to Fully Automated.

From the vSphere Web Client, right click the cluster to configure and select Settings.

Access the Manage > Settings tab and select the vSphere DRS option. Note that in this example the DRS Automation field is set as Fully Automated. Click Edit to change the DRS settings.

The DRS is now set as Manual.

Run the Migration-Assistant

If the VCSA to migrate uses an external Update Manager, the Migration Assistant must be running on the source Update Manager machine.

This tool facilitates the migration of the Update Manager server and database to the new upgraded VCSA. By default the Migration Assistant uses port 9123 but if the port is already in use by another service, it automatically finds a different free port to use.

Log in to the source Update Manager machine as an administrator and copy the migration-assistant directory from the VCSA Installer package.

vcsa60to65upgdeployvcsa07

Double-click VMware-Migration-Assistant.exe to run the tool.

vcsa60to65upgdeployvcsa08

Type the vCenter Single Sign-On administrator password. If no errors are displayed after the pre-checks, the source Update Manager system is ready for the upgrade. Leave the Migration Assistant window open until the upgrade of the VCSA finishes.

Stage 1 deployment

From the vCenter Server Appliance installer, click Upgrade option to upgrade an existing VCSA.

vcsa60to65upgdeployvcsa11

Click Next.

vcsa60to65upgdeployvcsa12

Accept the EULA then click Next.

vcsa60to65upgdeployvcsa13

Specify Source appliance parameters and the ESXi host that manages the source appliance. Click Next.

vcsa60to65upgdeployvcsa14

Click Yes to accept the self signed SSL certificate.

vcsa60to65upgdeployvcsa15

If you receive this error message it means the Migration Assistant is not running on the VUM server. Run the tool and try again.

vcsa60to65upgdeployvcsa16

Specify the target ESXi host to deploy the appliance and click Next.

vcsa60to65upgdeployvcsa17

Click Yes to accept the host’s SSL self signed certificate.

vcsa60to65upgdeployvcsa18

Type the VM name and specify the Root password. Click Next.

vcsa60to65upgdeployvcsa19

Based on your environment, specify the Deployment and Storage size then click Next.

vcsa60to65upgdeployvcsa20

Select the desired storage to save the VCSA and Enable Thin Disk Mode option to save space. Click Next.

vcsa60to65upgdeployvcsa21

Insert the network parameters and click Next. The assigned IP address is temporary and used during the upgrade process only. When the upgrade has completed the new VCSA will have same IP of the source VCSA.

vcsa60to65upgdeployvcsa22

Click Finish to start the deployment.

vcsa60to65upgdeployvcsa23

The appliance is being deployed to the target host.
