Content Validation Reports

  1. Instead of usual manual Content validation, we now just need confirmation that all Projects had automated validation run against them, and were clean before promotion.
  2. New Issues identified by the community from the previous Monthly Release.
    1. Decision on whether to fix the issues:
      1. VERY QUICKLY in time for this upcoming release?
      2. In good time for the next monthly release?
6.Mapping schedule

11.Risks

Atlassian tasks will change due to removal of workflow:

  • Devops to review the process with Maria to confirm what the new process should be, in order to prevent delays
  • Also need to confirm which stakeholder should be responsible for each task
  • UAT required for critical tasks such as locking the branches, etc

Time taken for overnight mapping server jobs:

  • September 2025 - Small increase in time taken on 8th August, but ony6 by 15mins so we'll just keep an eye on it to see if keeps going up or levels off....
  • August 2025 - small improvements from last time, so will keep an eye on this run and see if we need to make any more refinements
  • July 2025 - RICK STILL HAVING TO MANUALLY BOUNCE MYSQL DUE TO THE SWAP SPACE STILL FILLING UP DURING THE OVERNIGHT JOBS...
  • Chris is going to increase the SWAP space in the meantime, and open a ticket to investigate root cause in the long term...  Some changes made in May 2025...
  • 5th June 2025 - SWAP size still creeping up, so we'll check it again this cycle and see if any other action required...
  • 6th June 2025 - System came back online around 8:30am, so job seems to be back to running at roughly the normal time, so we will just continue to keep an eye on it for now...

Possible changes to dates required for October 2025 release schedule due to Jira/Confluence update
