Upgrade PX-Backup

To upgrade from the PX-Backup version 2.x.x to 2.2.0, you can use just the px-central chart.

Upgrade from 2.x.x to 2.2.0

To upgrade from PX-Backup version 2.x.x to 2.2.0:

Update your Helm repository:
```
helm repo update
```
Retrieve all custom values you used during the PX-Backup installation. Enter the following helm get values command to generate a YAML file, replacing the <namespace> and <release-name> parameters to match your environment:
```
helm get values --namespace <docs-namespace> <release-name> -o yaml > values.yaml
```

Delete the post install hook job:

kubectl delete job pxcentral-post-install-hook --namespace <namespace>

Run the helm upgrade command to upgrade PX-Backup, using the -f flag to pass the custom values.yaml file you generated above and replacing <release-name>, <repo-name>, and <namespace> parameters to match your environment:
```
helm upgrade <release-name> <repo-name>/px-central --namespace <namespace> -f values.yaml
```
Note: If the PX-Backup version is 2.0.0, then set the administrator password in the above helm upgrade command:
```
helm upgrade <release-name> <repo-name>/px-central --namespace <namespace> --set oidc.centralOIDC.defaultPassword=<current-admin-password> -f values.yaml
```

Consider you installed or upgraded an earlier PX-Backup version using the values.yaml, which you either:

generated from the Spec Gen wizard (or)
cloned from the PX-Backup Helm repository

In this case, you must specify the changes you made in the earlier version values.yaml in the new values.yaml that you use for installing or upgrading to PX-Backup 2.2.0.

For example: In the existing values.yaml, if the persistentStorage.storageClassName parameter is set with the value portworx-sc, then you must the set the same portworx-sc value in the new values.yaml.

Access permissions in PX-Backup 2.x.x

The permissions available to administrators from the PX-Backup 2.x.x versions to access resources are:

Can view and backup clusters that you added.
Can view all user created backups in the Backup page.
Can view all PX-Backup Security objects such as cloud credentials, backup locations, schedule policies, and backup rules of all users.
Cannot view all non-PX-Backup Security objects.

The access permissions available to a user in case of backup sync are:

If a user is the owner of a bucket, then the Backups page lists backups of all users who used that bucket.
If a user is a collaborator, then the user can view own backups only.

Upgrade from 1.2.x to 2.2.0

You cannot directly upgrade from PX-Backup version 1.2.x to 2.2.0. To upgrade PX-Backup from versions 1.2.x to 2.2.0, you must:

upgrade from one of the PX-Backup versions 1.2.x to 2.1.2
then upgrade from version 2.1.2 to 2.2.0

To upgrade from one of the PX-Backup 1.2.x version to 2.1.2:

Download the migration.sh file:

curl https://raw.githubusercontent.com/portworx/helm/master/single_chart_migration/migration.sh -o migration.sh

Change the migration.sh file permissions to make it executable:
```
chmod +x migration.sh
```
Update the Helm repository:
```
helm repo update
```
Search for the Portworx repository:
```
helm search repo portworx
```

Get the namespace where the PX-Backup components are installed:

helm ls -A | grep "px-backup-[0-9].[0-9].[0-9]" | awk '{print $2}'

Run the migration.sh file to upgrade to PX-Backup 2.1.2:

./migration.sh --namespace <namespace> --helmrepo <helm repo name> --admin-password <current-admin-user-password> --upgrade-version 2.1.2

After upgrading from PX-Backup 1.2.x version to 2.1.2, upgrade to version 2.2.0 by following the steps in the Upgrade from 2.x.x to 2.2.0 section.

If you are in air-gapped environment, then follow the steps below to upgrade PX-Backup from the prior versions to 2.x.x:

Clone the Portworx helm repository.

git clone https://github.com/portworx/helm.git

Make the migration.sh an executable file.

chmod +x /single_chart_migration/migration.sh

Get the namespace where the PX-Backup components are installed.

helm ls -A | grep "px-backup-[0-9].[0-9].[0-9]" | awk '{print $2}'

Modify the px-backup/values.yaml file matching your internal registry, repository, and image pull secret parameters. Pass the modified values.yaml file with the --helm-values-file option.

Run the migration.sh file to upgrade to PX-Backup 2.x.x.

./migration.sh --namespace <namespace> --helmrepo <current-directory/charts> --admin-password <current-admin-user- password> --air-gapped --helm-values-file <values.yaml>
