title: Azure DevOps server 2019 Migration to Azure DevOps services using Data Migration tool
body: <p>following the <a href="https://docs.microsoft.com/en-us/azure/devops/migrate/migration-import?view=azure-devops#identity-map-log" rel="nofollow noreferrer">document</a> for migration .... but in our case all user identities are maintained in <strong>Azure active directory</strong> and <strong>Azure ADDS</strong>(no on-premise AD is used).... so can i <strong>ignore</strong> the status of users in identityMap.csv file and go ahead with migration? will this impact post import</p>
