As with any significant change to your computer, you must back up your data. You can place important files in OneDrive, place them on an external hard drive, or use any other backup method you're comfortable with. If you have further questions about backing up your computer, please contact the ITS Help Desk. |

An operating system upgrade can take time. We recommend setting aside a full day for the process. While the active time you will be working on this will be minimal, you may not have productive access to your computer during your upgrade day. Any large upgrade of a computer presents a small chance for problems. If a problem occurs, ITS may need to intervene, and that may take some time. We strongly recommend choosing a time when you do not have a critical need for the computer within a business day of the upgrade if something goes wrong. For example, we would not recommend upgrading your computer the day before travel or during the weekend before an important conference. |
