how can we update bulk usernames in JIRA?

Hi Team,

How can we update bulk usernames in JIRA. We have tried the Rest API method. It has updated the usernames in JIRA, but when i checked the filter, i got the error.

Where the filters are directly associated with the usernames for eg. assignee= xyz@abc.com it throws error.

And where the usernames are not directly associated with the usernames for eg. assignee= ''current user'' these kind of  filters are working fine.

Please suggest some methods. If there is any plugin or any other method please suggest.

Regards,
