Plans on CentOS8 for UMD

UMD5 with CentOS 7 and 8

  • Pros
    • remove unsupported software in UMD-4 which makes keeping the repository consistent hard to the UMD team
  • Cons
    • Have to maintain 2 versions for a given period, along with a campaign to replace repo configuration on the sites is needed (replace UMD4/CentOS7 with UMD5/CentOS7)

Tentative draft plan

  • create UMD5/C7 with all products that offer support all over the next years (ideally until 2024)
  • once it's ready, ask sites to switch: UMD4/C7 -> UMD5/C7; this will provide sites with a supported OS including officially supported products at least until 2024, and could allow starting the slow retirement of UMD4 (SL6 retirement starting at end of 2020, C7 to be eventually used only for products phasing out and doomed to dismission).
  • UMD5/C8 gets filled meanwhile in parallel; you know, this relies very much on the product teams
