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

Jira Method

Jira Site import

Jira Cloud Migration Assistant

minus App data won’t be migrated

minus The migration will overwrite any existing data in your cloud site (except users and groups)

minus Users may need to be imported separately if managed externally

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

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

minus Need to allowlist specific IP addresses

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

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.

Hi There, 

It's Jason here. I'm from the Cloud Migration Platform team that builds both the Jira Cloud Migration Assistant and Site import. 

I just wanted to give an update on the Cons for the Jira Cloud Migration Assistant;

  • App data migration for Jira and Confluence is now in EAP (Early Access Program). We currently have 42 apps that are participating in the EAP with automated migration paths.
  • Support for JSM is coming soon with the EAP starting in the next 1-2 months.
  • Support for Advanced Roadmaps is coming later this year.
  • We are also improving support for specific entities. If you are working with an Atlassian Partner or with an Atlassian Cloud Migration Manager, you can request a feature we have in early development that will migrate all cross project boards and all filters.

If you are interested in joining any of the EAPs please sign up here

@Mirek which limitations would you like us to address first?

Mirek Community Leader Jun 29, 2021

@Jason Wong- Migrating Insight data for example. But if you ask to choose from the EAP list that you added above then I think Service Desk and definitively app data since both methods do not cover that..
