How Stellantis moved 150.000 Jira issues to the cloud, without downtime

When Stellantis  inherited an outdated Jira Server environment, simply moving everything to the cloud was not the answer. Years of duplicate fields, inconsistent workflows and legacy configuration would have moved with it. They wanted something better: a clean Jira Cloud environment without losing years of valuable history or disrupting its teams.

Together with ACA Group and Exalate, Stellantis migrated around 150.000 Jira issues in just 25 days, while cleaning up and restructuring its data along the way.
