Supported Operating Systems

Introduction

CSCS tests all new operating systems to ensure that they are compatible with our storage, authentication, patching and deployment systems.
Once an operating systems 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 continue support an operating system until it no longer receives security updates from its manufacturer. When this happens we are unable to make sure the device will remain secure, so where possible we encourage a device to upgraded to the latest operating system. Where this is not possible we may need to limit access on our network, to mitigate the security risk

Key to Support Levels

Not yet supported	The product has recently been released The product is undergoing testing for compatibility CSCS recommend that you do not use this product CSCS will not support or deploy this product
Early support	The product has been tested for use with core CSCS Services (authentication, storage, patching) Issues may be present in certain use-case scenarios Care may be needed when upgrading to this product Some support staff are familiar with this product Documentation is minimal The product can be installed upon request to technical users that accept slower response times and can cope with potential problems encountered
Full support	The product is current The majority of support staff are very familiar CSCS Services are tested for compatibility with this product CSCS maintains deployments for this product
Reduced support	The product is no longer current Support staff may have lost familiarity with using this product Compatibility problems with other applications or systems are likely CSCS Services are no longer tested to ensure compatibility CSCS will not deploy this product unless in exceptional circumstances CSCS will assist you in moving to a fully supported platform
Unsupported	Compatibility problems expected Represents a security risk CSCS will not support or deploy this product Once we contact the owner about an unsupported operating system: CSCS will assist you in moving to a fully supported platform (our hourly rate may apply) CSCS will restrict access if there is no progress within 30* days of consultation CSCS will decommission if there is no progress within 60** days of consultation

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.
