Upgrade

To perform the actual upgrade you should use the same command as the test command described earlier minus the --dry-run=server flag, for example like this:

helm upgrade --install uepe digitalroute/usage-engine-private-edition --atomic --cleanup-on-fail --version 4.0.0 -n uepe -f valuesFromSystem.yaml

If the upgrade was successful, the output will look like this:

helm upgrade --install uepe digitalroute/usage-engine-private-edition --atomic --cleanup-on-fail --version 4.0.0 -n uepe -f valuesFromSystem.yaml
Release "uepe" has been upgraded. Happy Helming!

Scale up the platform stateful set again so the platform starts back up using the following command:

kubectl scale --replicas=1 sts/platform -n uepe

After Upgrade

When the Usage Engine installation has been upgraded, ensure that any ECDs supporting rolling upgrade are still running as expected. If there are ECDs that have been configured for manual upgrade before the upgrade, see the section below.

Also ensure to enable any batch workflow groups again so that the batch processing can start again.

Manual Upgrade of ECDs

If you configured any ECDs to manual upgrade before the upgrade, follow these steps to upgrade these ECDs when the regular upgrade is completed:

1. Login to Desktop Online, see Desktop Online User Interface (4.3).

2. Go to the EC Deployment Interface (4.3) in the Manage view in Desktop Online.
   You will see a warning symbol next to the relevant ECDs.

3. Click on the ECD(s) to view the warnings. If there are ECDs that need to be upgraded, you will see a Message saying that it needs to be upgraded for each ECD.

   

4. Go back to the list of ECDs, click on the three dots to far right in the ECD row, and select the Upgrade option in the pop-up menu.
