Practices
The Configuration Manager for Jira app (CMJ) can migrate Project with issues along with the associated attachments. The Configuration Manager app is designed to support the export and import snapshots from different Jira versions. You can migrate projects from one Jira version to another.

Example: Jira source instance is on v7.8.0 and the target is on v8.10.0. Then CMJ Works perfectly. However, if the Jira source instance is on v8.10.0 and the target is on v7.9.0, the CMJ might not give accurate results.
Please check the compatibility matrix to make sure the version of the Configuration Manager for Jira (CMJ) is identical between the data center Jira instance and server instance.

If the Jira versions are close they don't differ in any major features and 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 could get the same set of features and object support.
Example: Jira source instance is on v7.8.0 and the target is on 7.9.0. CMJ is absolutely safe to create and deploy valid and full snapshots.
It is always suggested to check the compatibility matrix to make sure the version of the Configuration Manager for Jira (CMJ) is identical between the data center Jira instance and server instance.
