The JMCF app has an automated migration path and can be migrated from  Jira Data Center ; migration requires JMCF for Jira Data Center version 2.5.1 or later. Migration is currently supported using  Jira Cloud Migration Assistant (JCMA)  automation only.  Be aware that  JMCF  migration using JCMA is currently in Beta, so you may wish to test the JMCF migration in a trial or test Cloud instance.   Note:  If you have already migrated to the Cloud and need information regarding how to fix errors, see the  Post Migration page .  Before you start Make sure you are running  JMCF for Data Center  version 2.5.1 or later. Review the  Feature comparison  between  JMCF for Jira Data Center  and  JMCF for Jira Cloud .  Read and follow the instructions in  Atlassian’s documentation on Jira Cloud Migration Assistant (JCMA) . Please note: The Atlassian APIs do not enable the transfer of large numbers of custom fields; for larger instances with numerous custom fields, you may need to migrate them in batches. Due to a bug in JCMA, field context migrations are limited. For custom fields with more than one context, JCMA will only migrate the first context. Due to the difference in supported scripting languages between Jira Data Center and Jira Cloud, scripted custom fields will need to be manually recreated;  scripts will need to be rewritten in JavaScript . Formatting applied in Jira Data Center will not be migrated to Jira Cloud - only the definition of the custom field will be migrated.  You are viewing the documentation for  Jira Cloud .
