Selection criterias

Machines with unsupported operating systems should be upgraded. However:

  1. For Workstations/Remote Workstations with memory less than or equal to 2GB, the target upgrade will be Lubuntu 12.04 (Supported until Apr, 2017)
  2. For Workstations/Remote Workstations with memory above 2GB, the target upgrade will be Ubuntu 14.04 (Supported until Apr, 2019)
  3. 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:

Planned Upgrade is either to Lubuntu 12.04 or Ubuntu 14.04 for Workstations/Remote Workstations or Centos 6.5 for Servers.
