Now the administrator want's to verify as well as document the changes to be applied to the live Jira system prior to actually applying those.
The following diagram illustrates the general steps, under the assumption, that the test Jira system is not attached to the live Confluence system as well as, e.g. the Confluence Source Editor by Atlassian Labs is installed.
