Migrating user data on Ubuntu from 10.1.3 or later

When you want to use the data, which was in your earlier version, in a new version of Test Hub, you can migrate those user data..

Before you begin

You must have upgraded Test Hub to a new version.

The following table lists the variables that you must replace with the actual value in the command.

Variables	Description
{main}	The name of the release that you provided during the installation of Test Hub.
{backup-release}	The Helm release name of Test Hub where you store the backup data.
{target-release}	The Helm release name of Test Hub where you want to restore the data.
{backup-file-name}	The name of the backed-up file that you saved.

The devops-system is the name of the namespace that is created during the setting up of the k3s environment.

Run the following script from the ibm-rtas-case/inventory/ibmRtasBase/files directory to create a directory that contains metadata related to the Persistent Volume Claims and their Persistent Volumes:
```
sudo backup.sh create-pvc-links
```
Stop the Kubernetes cluster by running the k3s-killall.sh command.
Restore the backed-up user data by running the following commands:
```
sudo ./backup.sh restore [options] {backup-file-name}
```
You can use the following parameters along with the restore command:
Restart the Kubernetes cluster by running the systemctl start k3s command to start Test Hub.
Run the following script from the ibm-rtas-prod/files directory to create all the missing databases:
```
migrate.sh create-missing-dbs {{main}}
```
Note: You can expect the output of the command to contain several errors on objects that already exist. They do not indicate a problem with the execution of the script.
Run the following script from the ibm-devops-prod /files directory to verify and test the installed instance:
```
ibm-devops-prod
                                            /files/helm-test-diag.sh {main} -n devops-system
```

You have migrated the user data from the earlier version to the new version.

You can perform the following tasks:
