SL6 Worker Nodes Deployment Status

Timeline

The following timeline was agreed with all the experiments: Alice, Atlas, CMS, LHCb

• *Before 1st June 2013*
  • Shared sites that support Atlas are strongly encouraged to test but not to upgrade
  • Sites not supporting Atlas can go instead ahead also with the upgrade if they are ready
• Between 1st of June 2013 and 31st October 2013 the bulk of WLCG resources should be moved to SL6
• After 31st October 2013 only a tail of sites should remain
