We Marked an Epic as Done but we want to change it back to In Progress.
The web has many examples of using the Tool "Bulk Changes" on just the one Epic to change it's Epic Status back to In Progress, or at least not set to Done.
Our project is using the Cloud based JIRA and there isn't ever a Bulk Changes option available. Note: our organisation has the old JIRA (not cloud based) and It's possible to find Bulk Changes in the projects on the old platform. It doesn't appear that the Epic Status can be changed from Done.
