MW OS support details


From the Dec GDB summary presentation:

  • RHEL, CentOS Stream and 100% Enterprise Linux Clones (ELCs) should be treated equally
  • WLCG sites should plan migrations before 7 EOL (mid 2024)
    • From 7 to 9 seems promising during the period 2H 2022-2023 subject to middleware availability
    • CS9 already available, RHEL/ELC 9s also or coming soon
    • 8 may also be used already as needed for hardware compatibility or functionality

MW product teams can use any EL9-compatible distribution → collectively captured as EL9 (or CS9 in some places).
