Over the next week or so, the Network Services team will be upgrading the existing VSphere 4.1.x ESX hosts supporting virtual servers to VSphere ESX version 5. This upgrade will solve some compatibility issues we’re facing as we continue to virtualize existing physical servers. The upgrade should not negatively affect existing virtual machines or the services hosted on them and, therefore, will be done during normal business hours. The ESX hosts supporting the VDI environment will not be upgraded at this time, so there should be no impact to the virtual desktop systems either.

Please let me know if you have any questions.
