Upgrading Overview

The upgrade procedure that you complete depends on whether the N1 Service Provisioning System 4.1 is running on an operating system version that is supported for the N1 Grid Service Provisioning System 5.0. Occasionally, new versions of the N1 Grid Service Provisioning System no longer contain support for operating systems that were previously supported.

Upgrading Requirements

When upgrading any of the N1 Grid Service Provisioning System applications, the new server on which you install the 5.0 application must meet the following requirements:

• Operating System – The operating system on which you run the 5.0 application must be the same type of operating system on which you were running the 4.1 application. For example, you can migrate a Master Server running on Red Hat Linux 7.2 to a Master Server running on Red Hat Linux Advanced Server 2.0. You cannot migrate a Master Server running on Red Hat Linux 7.2 to a Master Server running on any version of the Solaris OS.

• Hardware Architecture – The hardware architecture of the server on which you run the 5.0 application must be the same as the architecture on which you were running the 4.1 application. For example, you can upgrade a Remote Agent from a SPARC based server running on the Solaris OS to another SPARC based server running on the Solaris OS. You cannot upgrade a Remote Agent from a SPARC based server running on the Solaris OS to an x86 based server running on the Solaris OS.

• User Ownership of Application – The 5.0 application must be owned by the same user that owns the 4.1 application. For example, if you installed the 4.1 Master Server and assigned ownership to user foo, then the 5.0 Master Server must have user foo assigned as its owner.

Upgrading – Process Overview

The following process overview describes the tasks necessary to properly upgrade from the N1 Grid Service Provisioning System 4.1 to the N1 Grid Service Provisioning System 5.0.

1. Determine whether the servers that you are upgrading meet the minimum requirements to run the N1 Grid Service Provisioning System 5.0.

   See Chapter 2, System Requirements for the N1 Grid Service Provisioning System 5.0.

2. Choose the Master Server upgrade instructions for your operating system.

   • If you are running the Master Server on Red Hat Linux 7.2, 7.3, or 8.0, follow the instructions in How to Upgrade a Master Server From an Operating System That Is No Longer Supported.

   • If you are running the Master Server on any other operating system, follow the instructions in How to Migrate Master Server Data From Supported Operating Systems.

3. Complete the instructions to upgrade the Master Server.

4. Identify any servers that are running Remote Agents and Local Distributors on operating systems that are not supported by the N1 Grid Service Provisioning System 5.0. See, Supported Operating Systems

5. Upgrade those servers to an operating system that is supported by N1 Grid Service Provisioning System 5.0.

6. Complete the instructions to upgrade the Remote Agents and Local Distributors.

   See, Upgrading Remote Agents and Local Distributors

7. CLI Clients do not need to be upgraded. Simply install the 5.0 version of the CLI Client and uninstall the 4.1 version.
