CIT recommends DELAY in upgrading Cornell-owned computers to El Capitan; Windows 10
Cornell Information Technologies (CIT) recommends all users of Cornell-owned computers do not upgrade their systems to the latest versions of Mac and Windows operating systems until thorough testing for compatibility with centrally supported services is complete.
The IT Security Office (ITSO) is currently testing El Capitan, the latest version of the Mac OS, and Windows 10 for compatibility with centrally supported services. Critical software such as EZ-Backup and Symantec Endpoint Anti-Virus Protection do not yet fully support these new systems.
In general, anyone working on a Cornell-owned computer should not rush to upgrade to the latest operating system before talking with his or her Technical Service Provider (TSP). If upgrading to the latest version of an operating system is required for your role, the IT Security Office will work with you to find a solution that will accommodate both your need for the upgrade and the need to maintain a secure computing environment for Cornell.
Technical Service Providers across campus should understand what central services have yet to be updated by vendors before upgrading to the very latest OS on a system. There is a natural lag between the release of a new operating system and when it can safely be installed on a Cornell computer as the vendors must update and test, and then the service providers at Cornell have to do the same to ensure functionality in the Cornell ecosystem.
