Dirac - Andrei
+ 2 patch releases: v7r0p52, v7r1p35
+ v7r2 done!
  python3 client
  client can be installed through pip install and conda
  -> adapt COMDIRAC, VMDIRAC and CTADIRAC!
+ OAuth to be updated after v7r2
+ Jupyter notebooks needs OAuth (above)
+ DIRAC/Go is stopped

EGI/FG services merged on March 22nd
+ installed v7r1p32
+ some configurations and setup adjustments needed
+ MariaDB server performance
  -> stuck on Sunday, max connections exceeded
  -> understand if the original issue was due to Dirac connections or to some other experiment
  -> ask for a dedicated MariaDB server...
 + Enable ES monitoring -> Patrick, Michèle
 + Enable Pilot3, RSS
 + Overall quite smooth migration, a few hours of downtime on 2 days

Sorina for Biomed
+ Cloud resources used in a static way, VM declared with static IP as Dirac CE
  -> possible to do something more dynamic, as WeNMR?
  -> GridPP now responsible of VMDIRAC
  -> plans to work on this second half of April, Sorina plans a doodle
     will also talk issues with using a CE at Strasbourg
+ Pb Pilot3, not clear if used or not... strange behavior of "bash -l" launching scripts
  check configuration of pilot version for Biomed
+ 13 Avril Creatis Tutorial -> VIP, Dirac, Singularity
