We are troubleshooting problems with our Jira Server migration to Jira Data Center and we want to use the configuration manager plugin... however... we are unable to use the CM plugin due to license mismatch we have in jira server version. We have 2000 licenses of Jira Server but only 500 licenses of Jira Server CM. Is there a way to reduce the license from 2000 to 500 for our legacy Jira Server version so that we can get this plugin to work on old environment, then take a snapshot of the projects, and continue with the Data Center migration process.
