Snapshot compatibility between Jira versions

Snapshots created on versions of Jira before Jira 6.3 will remove all members of the "Transition Issue" permission in permission schemes when deployed on Jira 6.3 and above.

Some Jira versions introduce new configuration objects and remove others, so a snapshot taken on one version might not always work on another.
