- Installation of the server software
  To get started working with IBM® Rational® Test Automation Server, you must first install the server software.
  - Installation of the server software on IBM® Red Hat OpenShift
    You can find information about the tasks that you can perform to install the Rational® Test Automation Server software on the IBM® Red Hat OpenShift platform.
    - Prerequisites for installing the server software on IBM® Red Hat OpenShift
      You must complete certain tasks before you install Rational® Test Automation Server on the Red Hat OpenShift platform.
    - Installing the server software on IBM® Red Hat OpenShift
      You can install Rational® Test Automation Server on the Red Hat OpenShift platform that has the Kubernetes environment to run functional, integration, and performance tests. Rational Test Automation Server combines test data, test environments, and test runs and reports into a single web-based browser for testers and non-testers.
    - Installation of the server software in an air-gapped environment
      You can find information about the tasks that you can perform to install Rational® Test Automation Server on the IBM® Red Hat OpenShift platform in an air-gapped environment.
      - Prerequisites for installing the server software in an air-gapped environment
        You must complete certain tasks before you install Rational® Test Automation Server in an air-gapped environment on the Red Hat OpenShift platform.
      - Configuring the Bastion host
        You must configure the Bastion host to mirror the images of Rational® Test Automation Server from IBM Entitled Registry to the Red Hat OpenShift Container Platform (OCP) cluster.
      - Installing the server software in an air-gapped environment
        You might have an environment that has a high level of security and is isolated from the internet. In such a scenario, you can install Rational® Test Automation Server on the Red Hat OpenShift platform in an air-gapped environment.
  - Installation of the server software on Ubuntu
    You can find information about the tasks that you can perform to install Rational® Test Automation Server software on the Ubuntu platform.
  - Installation of the server software on Azure Kubernetes Service
    You can find information about the tasks that you can perform to install Rational® Test Automation Server on the Azure Kubernetes Service (AKS) platform.
  - Management of server features
    After you install the server software, you can manage certain features based on your requirements.
- Server software upgrade methods
  When you want to use the enhanced functionalities of Rational® Test Automation Server, you must upgrade Rational Test Automation Server to the latest version.
- Migration of user data
  You can find information about the migration limitations and methods when you want to migrate data such as projects, test resources, configuration details of integrated applications, and so on. You can migrate data that is generated in an earlier version of IBM® Rational® Test Automation Server after you upgrade to or install the latest version, and then use that data in the latest version.
- Backup and restoration of the server data
  You must back up all your server data before you uninstall the current version of the server software or upgrade to the latest version of the server software. You must back up the server data to avoid data loss or inaccessibility of data.
- Uninstallation of the server software
  When you no longer require Rational® Test Automation Server, you can uninstall the server software. You can uninstall the server software depending on the platform on which you installed the server software.
- Configuration of the server software
  You can find information about the tasks that you must perform after you installed the server software to configure Rational® Test Automation Server.
- Team space administration
  You can find information about team spaces including the initial team space on IBM® Rational® Test Automation Server along with the tasks that you can perform to administer a team space.

Installation of the server software in an air-gapped environment

You can find information about the tasks that you can perform to install Rational® Test Automation Server on the IBM® Red Hat OpenShift platform in an air-gapped environment.

If your Red Hat OpenShift Container Platform (OCP) cluster is within a restricted network with no access to the internet, then you can install Rational® Test Automation Server on such OCP clusters by using an air-gapped environment. To install Rational® Test Automation Server, unlike online installations, air-gapped installations require an internal registry to mimic a typical online installation by using images from your internal registry.

In an air-gapped environment, you can mirror the images of Rational® Test Automation Server from IBM Entitled Registry to the internal Docker registry that has access to the OCP cluster. With the help of a Bastion host that can connect to the internet and your OCP cluster, you can install Rational® Test Automation Server on the OCP cluster.
