Problem
When performing multiple migrations from the Jira Server/Data Center to the Jira Cloud using the JCMA (Jira Cloud Migration Assistance), it will duplicate the Xray custom fields:
...
These fields will consistently be duplicated, regardless of whether they share the same name. This behavior is inherent to Jira; unfortunately, there is no way to prevent it. Specifically, if two fields have the same name, the system will automatically append "(migrated)" to one of them, such as "Revision(migrated)." Please be aware that this behavior is beyond our control and is a standard Jira functionality. Xray Cloud will use the fields it created, not those that were migrated, but it will copy data from those that were migrated during the migration process.
How to prevent this?
To prevent duplicated fields, please ensure these fields are identical in both instances before the migration. Unfortunately, there is no way to prevent those duplicated fields
