During the recent T3 Steering Board meeting held in Dec '14 at ETHZ the T3 Institute representatives agreed about the complete migration of the T3 to SL6 by the end of Jan 2015 ; *the SL6 migration will silently happen behind the scenes without further notice from the T3 admins* ; the T3 users will just notice the shrinking of the SL5 =t3wn*= and the increasing of the SL6 =t3wn*=. Eventually a user job requesting a SL5 queue will get pending forever because of the lack a SL5 =t3wn=

In order to be ready for the end of the SL5 =t3wn*= age all the T3 users have to migrate to the SL6 =t3ui1*= servers and submit their jobs just from there to automatically send their jobs to the SL6 =t3wn*=

Following the SL6 =t3wn*= migration just the old SL5 =t3ui0*= will be left *as they are* but the direct SSH connection from Internet will be *prevented* ; at that time the T3 users will have to use the SL6 =t3ui1*= servers as a bridge to login into a SL5 =t3ui0*= server by SSH.

Furthermore the SL5 =t3ui0*= HW maintenance and monitoring won't be performed anymore ( no broken disks swapped, no broken RAM swapped, etc.. ) and we might recycle the SL5 =t3ui0*= HW components to repair a compatible broken SL6 =t3wn*=
