To be scheduled.

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/Kubuntu 12.04 32bit (Supported until Apr, 2017 see https://wiki.ubuntu.com/Releases)
  2. For Workstations/Remote Workstations with memory above 2GB, the target upgrade will be Ubuntu 14.04 64bit (Supported until Apr, 2019 see https://wiki.ubuntu.com/Releases)
  3. For Servers, the target upgrade will be CentOS 6 (Supported until November 30th, 2020 see http://wiki.centos.org/About/Product#fndef-f629e99f98d098d5979628e3a302a1b0579202ce-1)

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:

Some machines running Scientific Linux have unsupported libraries and hardware.

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