In the 6.6.8 version of CMJ, any version of Jira can be installed between v7.8.0 to 8v8.11.0 can be installed in Source the source and Targettarget, but the CMJ app version should be identical to v6.6.8 in at both source and targetplaces.

Another important point to remember is, if : If the Jira versions are different, then the target instance shouldn't be running on an older version than the source instance.

Example -If running Jira Source : Jira source instance is on v7.8.0 and Target the target is on v8.10.0, then . Then CMJ Works perfectly. However, if the Jira Source source instance is on v8.10.0 and the target is on v7.9.0, then the CMJ might not give accurate results.
