How to Upgrade Remote Agents and Local Distributors

If you are running Remote Agents and Local Distributors on an operating system version that is not supported by the N1 Grid Service Provisioning System 5.0, you first upgrade the server to an operating system that is supported by both the 4.1 and 5.0 versions of the N1 Grid Service Provisioning System. Then, you use the browser interface to upgrade all of the Remote Agents and Local Distributors in your network. After the applications have been upgraded, you can then upgrade your servers to numerically higher versions of the operating system, if they are supported by the N1 Grid Service Provisioning System 5.0.

For example, you are running a 4.1 Remote Agent on a Red Hat Linux 7.1 server and you want to upgrade that server to Red Hat Linux 3.0 Advanced Server. First, you need to upgrade the server to Red Hat Linux Advanced Server 2.1, which is supported by both the 4.1 and 5.0 versions of the N1 Grid Service Provisioning System. Second, upgrade all of the Remote Agents by using the browser interface to the Master Server. Finally, upgrade the server to Red Hat Linux 3.0.
