DC -> Cloud ID mappings outside app migration

Cloud Migrations

Is there a way to obtain ID mappings for my DC to Cloud migration? Fields, users, everything else?

I am aware of the docs at About the cloud migration platform | App migration platform, but they appear to be all about app migrations. I’m not asking as an app developer here, just someone who needs this information for something post migration.

Hi @KonradGarus1,

The mapping are only available to apps that migrate, as they require a transferId for access. Once the migration has competed, and the app transfer is settled, then there’s no more access to the mappings.

If you need them outside of a migration, you’ll need to create your own tooling to end them from on-prem and work out your own way to link them to the cloud equivalent.

James.

Hello @KonradGarus1
DC to cloud mapping can be downloaded into a csv file using API to Fetch ID Mappings from Jira Cloud Migration Assistant | Migration | Atlassian Documentation API

This api requires your server/dc credentials and also need to know the cloudSiteUrl to which you are migrating.

Here is how you can make a call
server.or.dc.base.url/rest/migration/latest/report/id-mappings?cloudSiteUrl=destination.cloud.url&invalidateCache=false

Here is a sample response
