Issue Summary

When migrating from Server/DC to Cloud using Migrated all the Data at Once the emojis are not correctly rendering on ticket summaries.

Steps to Reproduce

1. Create a Jira Software Project with one issue on Serve/DC
2. On the ticket summary, add emojis by right-clicking in the summary and selecting the emoji
3. Create a migration plan and choose the migrate all data at once method.
4. Run the pre-checks and finish the migration.

Expected Results

The emojis should have been migrated and shown as in the source.

Source instance

Actual Results

The emojis are not migrating and have been changed to unreadable characters.

Destination site

By running the following API command on the source site:

https://<BASEURL>/rest/api/latest/issue/<issuekey>

It was identified that the emojis were stored in Unicode values.

"summary":"Issue test \uD83D\uDE31\uD83D\uDE0E \uD83D\uDE31"

The JCMA doesn't properly export the Unicode values, and the result in the entities.xml file after the migration is like this:

<Issue id="10401" key="VAL-2" number="2" project="10100" reporter="username" assignee="username" creator="username" type="10004" summary="Issue teste ���� ��" description="vvv$" priority="3" status="10000" created="2023-09-11 11:25:00.419" updated="2023-11-02 10:23:10.491" votes="0" watches="1" workflowId="10401" archived="N"/>

Workaround

This issue is only affecting the Migrate all Data at Once method.

That being said, the suggested workaround is migrating the projects using the Choose What to Migrate method.

Until a fix is worked out, you can contact Atlassian Support for a report of affected Issues, post-migration.
