What are the potential challenges you might encounter when exporting and importing custom fields in JIRA?

Exporting and importing custom fields in JIRA can present several challenges. One common challenge is ensuring consistent field mappings between the source and destination systems. Differences in field names or configurations can lead to data being imported incorrectly or not at all. Another challenge is maintaining data integrity during the export/import process. Data may be lost or corrupted if not handled properly. Additionally, compatibility issues with custom field types between JIRA instances can arise, causing errors or data loss during the import/export operations. It's essential to carefully plan and test the export/import process to mitigate these challenges and ensure a successful migration of custom fields in JIRA.
