15 January 2024 Update

Hi,
I am happy to share that Cloud-to-cloud data copy now supports the movement of team-managed projects across Jira Work Management and Jira Software products. More details here: https://community.atlassian.com/t5/Jira-Cloud-Admins-articles/Creating-more-flexibility-in-cloud/ba-p/2456212

We should be able to support team-managed projects in Jira Service Management projects in the next 4 months. Once we do, we will close this ticket.

Original description

According to What migrates in a cloud-to-cloud migration for Jira, the Jira Cloud to Cloud Migration Assistant does not support the migration of Team-Managed projects.

As a workaround, one could convert Team-Managed to Company-Managed projects and then migrate, however, there's severe data loss associated to it, specially when it comes to Story Points.

It would be great if the tool could migrate these type of projects so administrators don't need to deal with data loss when merging Cloud instances or when migrating data from one Cloud to another.
