Description
### Value Prop
Upgrading GitHub Enterprise Server now requires about 20 minutes less downtime. Starting with GHES 3.21, pre-upgrade steps that previously ran during the maintenance window can now be run beforehand, while the appliance is still serving traffic.
### Expected Outcome
Downtime during upgrades is one of the most significant friction points for GHES customers. Starting in 3.21, the pre-upgrade steps run while the appliance is still live, moving ~20 minutes of work outside the maintenance window and reducing total downtime accordingly.
Contributor guide
Research direction
No files, tests, or entry points are identified in the roadmap issue. Start by clarifying the GHES 3.21 upgrade workflow and implementation scope; done should mean the pre-upgrade work runs while the appliance serves traffic and reduces maintenance-window downtime by about 20 minutes.
