How to export checklist items from Jira

Use one of the following ways of exporting checklist data out of Jira:

• Backup Jira (export Jira issues)
  That is useful for backup purposes or when migrating to other Jira instance.
  Don’t use this way to export checklist data when migrating to other plugin or non-Jira system.

• Use Jira REST API to read issues (checklist)
  That is useful if you want to migrate Jira issues to a non-Jira system or migrate checklist to other plugin or system.
