Issue Summary

If you move issues between two Team-managed projects, Jira will clear all values from custom fields even though you select to retain these values:

Steps to Reproduce

1. Access the issue for a Team-managed project
2. Click on the top-right menu (. . .) > Move
3. Select another Team-managed project and click to Retain values

Expected Results

The custom field values should be moved to the new project

Actual Results

The custom fields appear blank

Workaround

Instead of using Bulk move options, One possible workaround could be to create an automation rule with

1. Manual trigger OR Scheduled trigger(for bulk movement)
2. Add Clone issue action or Create issue action
3. Choose all the custom fields in the "Choose fields to set" section
4. Use triggerIssue.customfield_<customfield_id> smart value in the destination fields

This will copy over the value from source issue custom fields to destination issue custom fields
