Atlassian's decision to sunset Opsgenie by April 5, 2027, compels users to migrate to alternative incident management platforms such as Jira Service Management (JSM), PagerDuty, or incident.io. Each option offers distinct advantages: JSM integrates well with existing Atlassian products, PagerDuty provides mature customization features, and incident.io offers a modern, Slack-native approach with quick deployment and transparent pricing. The recommended migration strategy involves a parallel run, ensuring zero downtime by operating both the old and new systems simultaneously. Migration complexity varies, with incident.io offering the fastest setup and ease of use. The total cost of ownership should consider not only subscription fees but also implementation, training, and potential revenue impact due to migration-related downtime. As the Opsgenie sunset approaches, organizations are encouraged to plan early and execute migrations with precision to avoid service disruptions.
