Internal JIRA users, administrators, site admins, jira-servicedesk-users, jira administrators
If I delete internal jira users administrators, and jira administrators would something go wrong in JIRA?
If these are default groups, what is the difference between jira-adminsitratros, site-admins, administrators, internal jira users, and jira service desk users groups?
If all of these groups are not default groups, please list the groups that are default groups that come with JIRA and explain the difference between them.
Thank you.
