But for a migration a commercial license is needed on both the source and target Jira servers, as they are usually both production. If the license is needed only for the duration of a migration, you can purchase a short-term (monthly) one directly from us - please contact sales@botronsoft.com or open a license request at support.botronsoft.com.
Note: If you have a commercial Data Center license for Configuration Manager for Jira on your target instance you can request free monthly licenses for the source instances for the migration or use a trial license.
You can use a trial license for evaluation purposes only. The same trial license can be used on multiple instances for evaluation purposes.
