      David Sanders' Transition to 3.4

      • Worker nodes were easy
        • Still had glexec installed, had to remove first
        • Otherwise fine
      • SE already switched from bestman2
        • Also has frontier squid and gridftp
      • Already migrated to LCGMAPS
      • CE migration more challenging 
        • followed github steps
        • also removed bestman client
        • Started yum install; yum install hung 
        • restarted instructions on github from the very beginning; worked.
      • Note: have to follow instructions on github upgrade site to remove bestman2, yum removal of bestman* doesn't work  http://opensciencegrid.org/docs/release/release_series/#updating-from-osg-31-32-33-to-33-or-34
