-To be scheduled. 
- 
- 
-==== Selection criterias ==== 
- 
-Machines with unsupported operating systems should be upgraded. However: 
-  - For Workstations/​Remote Workstations with memory less than or equal to 2GB, the target upgrade will be Lubuntu 12.04 (Supported until Apr, 2017) 
-  - For Workstations/​Remote Workstations with memory above 2GB, the target upgrade will be Ubuntu 14.04 (Supported until Apr, 2019) 
-  - For Servers, the target upgrade will be CentOS 6.5 (Supported until November 30th, 2020) 
- 
-==== Situation ==== 
- 
-OpenSuSE dropped or will drop support for most of the OS versions we have. As a result the machines are 
-at security risk and most of the libraries will stay obsoleted and without bugfixes. Sources: 
-  * https://​en.opensuse.org/​Lifetime 
-  * https://​en.opensuse.org/​Evergreen 
- 
-Planned Upgrade is either to Lubuntu 12.04 or Ubuntu 14.04 for Workstations/​Remote Workstations or Centos 6.5 for Servers.
