Issue Summary

When a C2C migration fails, there is no error detail shown in the browser UI. It would be helpful if customers can see where the issue lies as often it may result in fixing it before contacting Atlassian Support.

An example is failure of a migration due to dependencies such as issue types for boards. Once the message was found by Support and share with the customer, the issue was resolved. However, no message or error was shown to the customer in the UI upon failure.

This is reproducible on Data Center: not applicable

Steps to Reproduce

1. Run a Cloud to Cloud migration of Jira Projects
2. Migration either shows failed or incomplete status
3. No error or message shows up in the browser to indicate where the issue may lie

Expected Results

An error or message showing what could've caused the migration to fail can help the customer to avoid contacting Atlassian Support just to understand what has gone wrong with the migration.

Actual Results

No error or mesage is shown in the UI when a migration fails. As opposed to a server-to-cloud migration where application logs may have some clues, the customer has no way of determining what went wrong except contact Atlassian Support.

Workaround

Customer must contact Atlassian Support.
