Jira Cloud Migration Assistant vs Jira Site Import

Deciding on a migration methodology is highly dependant on your requirements. As a customer/partner you want to ensure that you are 100% confident with the choice you make before moving forward with the migration.

Compare cloud migration methods highlights the benefits and limitations of both tools which is also copied on the article below.

Moreover, you want to read carefully through What gets migrated with the Jira Cloud Migration Assistant and what doesn’t as it sets the expectations beforehand.

You can also attend a Demo on Cloud Migration which showcases how to execute a cloud migration, and give recommendations on the best practices and tools to use along the way.

Additional steps need to be taken to migrate the app data. You can view Atlassian Marketplace apps that are available in cloud with migration paths and also sign up for Early access program for app migration using Jira and Confluence Cloud Migration Assistants

minus You can’t choose what you do and don’t want to migrate (for example, only select projects)

minus Because this method is “all or nothing” large amounts of data can result in longer downtimes


minus App data won’t be migrated

minus Jira Service Desk will not be migrated (use Jira Site Import or CSV import instead)

minus Advanced Roadmaps (Portoflio) will not be migrated

minus You’ll need to be on a supported self-managed version

minus Specific entities (eg. custom fields, cross-project boards, dashboards, etc.) are not migrated

Thank you @Amna Elabbas for comparing this. It would be definitively useful. The biggest problem however is that both methods still have limitations.. 

Amna Elabbas Atlassian Team May 31, 2021

Hi @Mirek , we are constantly improving our methodologies and while both methods indeed have limitations, they are both very powerful and demonstrated success for customers' use cases. It's crucial that the customers/partners have the right migration strategy in place to workaround the limitations.
