The following are the steps in the life cycle of support for computer operating systems:

  1. Early Adopter/Not Recommended. In this phase, a new operating system has recently been released by the vendor and is untested in our environment. Customers may see compatibility or functionality issues and IS staff will do "best effort" support. Community Network will be conducting formal testing of the new operating system to ensure stability and compatibility within the  enterprise environment prior to transitioning to the Optional stage.
  2. Optional (New). During this phase, Community Network staff will install the new operating system upon request only, and will fully support it.
  3. Standard/Recommended. During this phase, Community Network staff will install this operating system on all new computers and when performing a rebuild (unless the customer requests a different operating system).
  4. Supported. During this phase, Community Network staff will install the old operating system upon request only but will recommend that customers upgrade to a newer operating system.
  5. Decommissioning. During this phase, the vendor is no longer providing updates and Community Network will actively work with customers to upgrade their systems.
  6. CN unsupported. This includes operating systems that are no longer maintained by the vendor, as well as home versions of operating systems that are not appropriate for university-owned computers.
