ES7 deployment strategy

Effort Coordination

This blended project upgrades our outdated and unsupported Elasticsearch from version 1.5 to version 7 in each of our services. We will need a resource from each owning squad to do a final review and deploy of the Elasticsearch upgrade for their owning service. The expected effort is:

  • Squad engineer’s review of PR: 2-5 hours depending on the complexity of the service’s use of Elasticsearch (PR will already be reviewed carefully by @Diana Huang or @Michael Terry (Deactivated))

  • Squad engineer’s deploy and monitoring of the migration: 2-3 days depending on production rollout
