Software Installation and Upgrades

Recommended Actions to Prepare for Upgrading an Operating System

Before upgrading a computer to another operating system, there are several recommended steps to take.

• Check to see if you want to upgrade to the new operating system.
  Software vendors usually have web sites to help you decide if the upgrade is for you. Depending on your needs and the operating system that you are currently running, they will use the sites to try to help you decide if an upgrade is in your best interests.
• Confirm that your computer hardware meets the minimum requirements the new operating system.
• Check to see if your hardware and software are compatible with the new operating system.
• Back up your important files.
  Backing up important files such as your documents, spreadsheets and slideshows is always a good idea. Even if you do not intend to upgrade your computer or make any changes to it, it is considered good practice to back up as often as you can to protect your files. Backing up can be as simple as putting your files onto removable media, such as CDs, DVDs, or flash drives, or using a tape back-up if you have access to one.
• Install hardware and software updates, if needed.
  Malicious hackers repeatedly find vulnerabilities, or "holes," which they use to exploit computer software. As a result, vendors develop patches to fix these vulnerabilities. Customers are responsible for downloading and installing these patches and configuring software correctly.
  Information Technology strongly recommends downloading and installing patches as often as necessary.
  • Customers using Microsoft Windows can find their updates at
    windowsupdate.microsoft.com/
  • Macintosh users can find updates at
    www.info.apple.com/support/downloads.html
• Check your system for viruses.
  
  Make use of anti-virus software to check and clean your computer of viruses. Like backing up, this is considered a good practice to maintain at all times, not just when you are going to upgrade your computer.
• Plan ahead for rolling back.
  Many operating systems do not provide an uninstall feature. You may not be able to return to your previous operating system unless you completely reinstall your older operating system and all of your programs.
