| # Zero-downtime Gerrit upgrades | |
| How to upgrade a Gerrit production instance without pulling the plug. | |
| Even without having a fully redundant multi-master setup like Google | |
| it is possible to perform a full Gerrit upgrade without having to | |
| interrupt incoming traffic. | |
| Learn how GerritHub.io managed to: | |
| - upgrade its DB | |
| - migrate data-center from Europe to America | |
| - update Gerrit binaries and plugins | |
| - performed full reindex | |
| ... and keeping its 100% availability at the same time. | |
