Hello,
I'm using JIRA 5.2 and I performed an update from <JIRA Suite Utilities> with the Universal Plugin Manager. The following text has been added in red near JIRA Suite Utilities INCOMPATIBLE - UPDATE REQUESTED. The add-on is for JIRA 6.0 and later release. See the attachment below.
My questions are:
1/ What are the update impacts on my instance of JIRA?
2/ Is my instance of JIRA still working correctly? Can I continue to use JIRA in this state?
3/ Should I roll back to a previous version of the add-on? Is it possible? if yes how?

Thank you in advance.
