Introduction

CSCS tests all new operating systems to ensure that they are compatible with our storage, authentication, patching and deployment systems. Once a product has passed core testing we make it available on request via the Service Desk for our more technical users while we prepare deployments, train support staff and prepare documentation.

When everything is ready and we are able to offer comprehensive support, we will make it generally available.

We will generally continue support an operating system until it no longer receives security updates from its manufacturer, but as newer versions are released, we inevitably become less familiar with older operating systems,

* Public facing servers would be locked down at the firewall so no public access is possible. Reduced user access limited to just the a small number of hosts (CSCS server team plus server owner or developers that need access to migrate). VM's would be turned off and remain on VMware for a further 30 days. 

** If there is no contact or progress with the customer after 60 days, physical equipment would be shutdown, VM's would be destroyed.
