I am looking for an option in Jira change management to keep a track of all changes made during upgrade , ie I want to upgrade a product from Version 1.0 to 1.1 and then 1.2 . Here, I need to have details of changes made in each steps such as patches applied , configuration changes made etc. So later , team can get history of changes in each upgrade steps . It would be helpful if someone can suggest best solution / option in Jira (like calendar ) .
