It is always ideal to have the same version of Jira running on both source and target instances. However, with the latest version of Configuration Manager for Jira app one can have two different Jira versions on the source and target instances provided the version of Configuration Manager for Jira app is identical.
Example: Configuration Manager for Jira v6.13.5 works for Jira versions between 8.0.0 and 9.11.1. In the 6.13.5 version of Configuration Manager for Jira(CMJ), any version of Jira can be installed between v8.0.0 and v9.11.1 in the source and target, but the CMJ app version should be v6.13.5 at both places.
Important: If the Jira versions are different, the target instance should not be running on an older version than the source instance.
Example: If the Jira source instance is on v8.0.0 and the target is on v9.11.1, CMJ works perfectly. However, if the Jira source instance is on v9.11.1 and the target is on v8.0.0, the CMJ might not give accurate results.
If the Jira versions are close they don't differ in any major features, so it is absolutely safe to use CMJ to create and deploy 100% valid and full snapshots. Also, you don't need to use the same version of CMJ, but it is recommended to use close versions of the CMJ if the same versions are not possible, so you can get the same set of features and object support.
Example: Jira source instance is on v8.0.0 and the target is on v8.1.0, CMJ is absolutely safe to create and deploy valid and full snapshots.
If the Configuration Manager for Jira(CMJ) versions are different in source and target, you need to make sure that the Configuration Manager version on the target instance needs to be the same or newer than the one in the source.
Example: If the CMJ version is 6.1012.0 5 in the source and 6.1113.1 5 in the target, then the deployment will be successful, but if the CMJ version is 6.1113.1 5 in the source and 6.1012.0 5 in the target, the deployment will not be successful.
It is always suggested to check the compatibility matrix to make sure the versions of the Configuration Manager for Jira (CMJ) are the same between the Target Jira instance and the Source Jira instance.
