Network Server Setup: Full versus Upgrade

One of the basic network operating system (NOS) installation choices is whether you want to perform a full installation or an upgrade installation. In some cases, you may be better off performing a full installation even if you’re installing the NOS on a computer that already has an earlier version of the NOS installed.

  • If you’re installing the NOS on a brand-new server, you’ll be performing a full installation that installs the operating system and configures it with default settings.

  • If you’re installing the NOS on a server computer that already has a server operating system installed, you can perform an upgrade installation that replaces the existing operating system with the new one but retains as many of the settings from the existing operating system as possible.

  • You can also perform a full installation on a computer that already has an operating system installed. In that case, you have the option of deleting the existing operating system or performing a multiboot installation that installs the new server operating system alongside the existing operating system. Then, when you restart the computer, you can choose which operating system you want to run.

  • Although multiboot installation may sound like a good idea, it’s fraught with peril. you should avoid multiboot unless you have a specific reason to use it.

  • You can’t upgrade a client version of Windows to a server version. Instead, you must perform a full installation, which deletes the existing Windows operating system, or a multiboot installation, which leaves the existing client Windows intact. Either way, however, you can preserve existing data on the Windows computer when you install the server version.
