Here’s a list of known issues that might affect your migration or the already migrated data.
Topic | Description |
---|---|
Data integrity | If your Jira Server site is highly customized, you may face additional issues when migrating. For example, if you have any required field with a null value the migration will fail because this is not supported on your Cloud site. We recommend cleaning up your instance data before migrating. |
Incomplete migrations and projects | An incomplete status means that some things have been migrated but there was at least 1 entity that we couldn’t migrate. For example, we might be able to migrate a project but 1 issue fails because there is a null value in a custom field. In this case, the project will show up as incomplete even though all the actual data is complete. Many times this status will not be a problem for your migration. Download the error logs to determine what is causing the failure. |
Changes on Server before migrating | If you make any changes on your Server site, wait at least 10 minutes before migrating to allow all data to be updated. |
Changing project keys | If you choose to change a project key on your Server before or during migration, make sure that all configuration, filters and boards are updated with the new project key before attempting a new migration. |
Links to projects and issues that aren’t included in the migration | If you have chosen to migrate in smaller batches, links to projects or issues that haven't yet been migrated will be missing until that linked item is migrated. |
History entries with missing references | If a history entry refers to a missing link or attachment, the history entry won't be migrated. If a linked issue or project is migrated at a later date, the history entry will be updated. |
Jira boards not returning correct results | The migration assistant does not check that the JQL issue filters on boards are returning the correct results after migration. If a board has a filter that mentions a project or field that is not yet migrated, the board may not return the same results after it is migrated. To fix this issue, edit the board's JQL filter after migrating. Learn more about board filters |
Problems with Jira Align after the migration | If you use Jira Align, you need to complete additional steps before, during, and after the migration. If you’re having problems, see the linked page or contact Atlassian Support. Learn how to migrate Jira Align |
There are two things you can check before running the migration:
Pre-migration checks
Pre-migration report
Pre-migration checks are a mandatory step of every migration. They make sure that your configuration is correct and that the data can be migrated to Cloud. Run pre-migration checks, review, and run a Jira migration
Here’s a brief description of statuses shown by pre-migration checks.
Symbol | Description |
---|---|
The check has passed. You can proceed with your migration. | |
You can proceed with your migration, but you need to be aware of a potential issue. Expand the warning messages to view details. | |
You can’t proceed with your migration until you resolve the error. Expand the error messages to view details. | |
The check wasn’t completed due to an unexpected error. Refresh the checks or contact Atlassian support. |
Here are common problems shown by checks and steps you need to take to solve them.

You’ve reached the limit of email aliases for a single email address | This check is shown when the number of email aliases related to a single primary email exceeds the limit of 10. An alias is a variation of the primary email, for example charlie+suffix@atlassian.com vs. charlie@atlassian.com. The limit exists on the cloud side and allows to create only 10 aliases per hour. Download CSV file When viewing the check, you can download a CSV file to help you resolve the issue. The file:
Goal Your goal is to change the aliases into individual emails or delete the corresponding users. It’s enough if you do it for aliases that exceed the limit. However, since cloud subscriptions are billed per user, you might want to delete or deactivate these extra users. Solve the issue To solve this issue, use the CSV file to identify the corresponding users and either update or delete them:

Problem summary | Problem Description | Solution |
---|---|---|
Unsupported custom field configuration | Migration of <custom_field_type_name> custom field type isn't supported. Therefore, the configuration for this field won't be migrated, and any items that reference it, such as workflow schemes and filters, may no longer work. | If you need this custom field, recreate it in your cloud site and use a CSV import to update the issues post-migration. Refer to the Adding additional entities with CSV section in this document: |
Unsupported custom field configuration | Migration of the <custom_field_name> custom field isn't supported. The value for this issue will not be migrated. | If you need this field value, use a CSV import to update the issues post-migration. Refer to the Adding additional entities with CSV section in this document: |
Unsupported issue type | During the migration, the <issue_type_name_A> issue type will be renamed to <issue_type_name_B> issue type. | Review the issue type after migration to ensure it functions as expected. Some JQL references may be affected and need to be updated after migration. |
Unsupported notification scheme | The notification schemes aren't supported and won't be migrated. | The default notification scheme will be assigned to each project in the cloud site. Review the permissions post migration. |
Missing configurations or references in the condition of the workflow | The workflow will be migrated. However, the condition on <transition_name> transition of the workflow will be skipped, which may impact the permissions in your cloud site. | Review the workflow post-migration to ensure that the permissions are set correctly. To identify workflows that might be affected during pre-migration, run SQL queries from this page: Troubleshooting errors and non-migrated entities with the Jira Cloud Migration Assistant |
Missing configurations or references in the transition of the workflow
| The <transition_validator_name> validator isn't supported. The workflow will still be migrated. However, the validator on <transition_name> transition of the workflow will be skipped, which may impact the permissions in your cloud site. | Review the workflow post-migration to ensure that the permissions are correctly set. To identify workflows that might be affected during pre-migration, run SQL queries from this page: Troubleshooting errors and non-migrated entities with the Jira Cloud Migration Assistant |
Missing configurations or references in the post function of the workflow | The <name> post function isn't supported. The workflow will still be migrated, however the post function on <name> transition will be skipped, which may impact the workflow in your cloud site. | Review the workflow post-migration to ensure it functions as expected. To identify workflows that might be affected during pre-migration, run SQL queries from this page: Troubleshooting errors and non-migrated entities with the Jira Cloud Migration Assistant |
Unsupported custom event type | The notification for the event type <event_type_name> isn't supported through migration (custom event issue). The value for this issue will not be migrated. | If you need this field value, use a CSV import to update the issues post-migration. |
Null filename for attachments | Attachments with a null value for the filename aren't supported and won't be migrated. | If you need this attachment on your cloud site, you need to first assign a non-null filename to the given attachment ID on your server and then run the migration. |
Unsupported gadget | This gadget isn't supported and won't be migrated. |
|
Partially migrated gadget | Found errors while migrating this gadget; therefore, it will be migrated without its configurations. For error details, refer to the log files generated when creating the support zip. |
