We are planning to migrate our custom ticketing system to Jira Service Management.
Is there an official method to import a large volume of companies, users, and tickets from our existing system into JSM? Should we rely on Jira's default REST API, or are there alternative options, such as a built-in import function (e.g., JSON or CSV-based import)? and mapping of data field b/n different managemnt tool.
We’d love to hear from the community about your experiences, challenges, and best practices for such a migration—particularly if you've moved from Zammad to Jira Service Management. Any advice or pointers to get started would be greatly appreciated
