Converting logins to AD federation in Jira Cloud, do we lose history?

[Tim]

Hi All,

Didn't find any answers to this, though the question has been asked.  We want to switch our Jira cloud access from username/password to AD federation.  My question is what happens with the reporters and assignees for all the existing task, stories, etc?  

Currently we login using our work email.  If our company domain is SoylentCorp, then our logons would be walter.sobchak@soylentcorp.com with whatever password the employee chooses.  

We want to switch this to using the employee's AD account, but not lose any history for existing tasks, epics, or confluence documentation.

Thanks for your help

Tim
