Upgrade Airgap Palette VerteX Installed on VMware vSphere

This guide takes you through the process of upgrading a self-hosted airgap Palette VerteX instance installed on VMware vSphere. Before upgrading Palette VerteX to a new major version, you must first update it to the latest patch version of the latest minor version available. Refer to the Supported Upgrade Paths section for details.

warning

If you are upgrading from a Palette VerteX version that is older than 4.4.14, ensure that you have executed the utility script to make the CNS mapping unique for the associated PVC. For more information, refer to the Troubleshooting guide.

If your setup includes a PCG, you must also allow the PCG to upgrade automatically before each major or minor Palette VerteX upgrade.

Prerequisites

Access to the Palette VerteX system console.
Access to the Palette VerteX airgap support Virtual Machine (VM) that you used for the initial Palette VerteX installation.
Refer to Access Palette VerteX to download the new airgap Palette VerteX installation bin and, if necessary, receive a link to the new OS and Kubernetes OVA.
Contact our Support Team at support@spectrocloud.com to learn if the new version of Palette VerteX requires a new OS and Kubernetes OVA. If necessary, they will provide you with a link to the OVA, which you will use to upgrade Palette.
A diff or text comparison tool of your choice.

Upgrade

info

If the new version of VerteX requires you to update the underlying OS or Kubernetes distribution, proceed with the steps one through four. Otherwise, start at step five.

Log in to vCenter.
Right-click the cluster or resource group that hosts your self-hosted VerteX instance and select Deploy OVF Template.
In the Deploy OVF Template wizard, at the Select an OVF template step, enter the link to the new OS and Kubernetes OVA that you received from our support.

Consider the following example for reference.
```
https://vmwaregoldenimage-console.s3.us-east-2.amazonaws.com/u-2204-0-k-12610-0.ova
```
At the Select a name and folder step:
- In the Virtual machine name field, append the r_ prefix to the prepopulated OVA name and remove the .ova extension.
  
  Consider the following example for reference.
```
u-2204-0-k-12610-0.ova >>> r_u-2204-0-k-12610-0
```
  info
  It is important that you follow this naming convention. Otherwise, VerteX will not be able to identify the OS and Kubernetes OVA and you will not be able to upgrade your VerteX instance.
- Under the Select a location for the virtual machine selector, choose the spectro-templates folder you created during installation.
Once the OS and Kubernetes OVA is available in your spectro-templates directory, you can terminate its deployment. Refer to the Deploy an OVF or OVA Template guide for more information on deploying OVAs in vCenter.
In your terminal, use the following command template to SSH into the Palette VerteX airgap support VM. Enter the path to your private SSH key, your username, and the IP or domain of the airgap support VM. The default username is ubuntu.
```
ssh -i </path/to/private/key> ubuntu@<vm-ip-or-domain>
```
Consider the following command example for reference.
```
ssh -i /docs/ssh-private-key.pem ubuntu@palette.example.com
```
Use the following command to switch to the root user account, which you need to proceed with the upgrade.
```
sudo --login
```
Use the following command template to download the new Palette VerteX airgap installation bin. Enter the username, password, and the Palette VerteX airgap installation URL you received from our support team. In the output file name, replace <version> with the Palette VerteX version you are downloading.
```
curl --user <username>:<password> --output airgap-<version>.bin <url-to-airgap-installation-bin>
```
Consider the following command example for reference.
```
curl --user <username>:<password> --output airgap-4.2.12.bin https://software.spectrocloud.com/airgap-v4.2.12.bin
```
Refer to the Additional Packs page and update the packs you are currently using. You must update each pack separately.
Use the following command template to execute the new Palette VerteX airgap installation bin.
```
chmod +x airgap-<version>.bin && ./airgap-<version>.bin
```
Consider the following example for reference.
```
chmod +x airgap-v4.2.13.bin && ./airgap-v4.2.13.bin
```
After the Palette VerteX airgap binary is verified and uncompressed, it uploads the updates to your existing Palette VerteX instance. This step takes some time to complete.
```
Verifying archive integrity...  100%   MD5 checksums are OK. All good.

Setup Completed
```
Once the airgap binary is executed, you will receive a Setup Completed success message.
Log in to the Palette VerteX system console.
From the left Main Menu, select Enterprise Cluster and then select the Profile tab.
Copy the configurations for your CSI, CNI, and Kubernetes layers to an external location for backup.

tip
If your Enterprise Cluster profile has configuration changes or additions, make sure to back up all the customized values to preserve them after the upgrade.
From the left Main Menu, select Administration > Pack Registries. Then, next to your spectro-packs registry, select the three-dot Menu > Sync.

Palette VerteX initiates a registry sync, which can take up to 30 minutes to complete.
From the left Main Menu, select Update Management. Once the registry sync is done, Palette VerteX will prompt you to update to the new version. Click Update.
In the Palette version update preview modal, from the left Main Menu, select the Kubernetes layer. The Incoming changes pane displays the changes that the upgrade introduces. The Current configuration pane displays your current layer configuration.

info
To complete the Palette VerteX upgrade, we recommend using an external diff or text comparison tool. Proceed with the following steps once you have the comparison tool available next to the Palette VerteX system console.
Copy the configurations from both Incoming changes and Current configuration panes to your comparison tool.
From your current configuration, transfer only those differences that are custom to your self-hosted Palette VerteX instance (for example, the podCIDR and serviceClusterIpRange values). Do not override any other changes or upgrades.
After you finish merging the configurations, copy the resulting configuration, and then paste it to the Current configuration pane in the Palette VerteX system console.
Repeat steps six through eight for each Enterprise Cluster profile layer.
In the bottom-right corner of the Palette version update preview modal, select Confirm.

The system console locks for a couple of minutes while the upgrade is applied.

Validate

Log in to the Palette VerteX system console.
On the Summary page, Palette VerteX should display messages that state You are using the latest version of Palette VerteX and On-prem system console is healthy.
