HI Folks, time is almost upon us.
This Saturday/Sunday (depending on your TZ) is when the migration and upgrade happens. Is everyone prepared for :- A) The amount of downtime - it will be several hours , including stopping new jobs from running to allow for in progress jobs to complete. B) the Maven JDK 1.7 issue. Workarounds have been mentioned on this list and I will document them on the Infra Confluence Wiki shortly. C) Plugin Upgrades - These will be upgraded both before, for those that are compatible with the current running version, and after the upgrade, to being them inline with the new Jenkins version. I will be on HipChat #asfinfra (https://infra.chat <https://infra.chat/>) all weekend should anyone have any questions before/during/after.
