I have two users with a similar name/email (differentiated by adding1 to user 2s email/username) I have edited user 1 with the email address of user 2 and subsequently linked all pages and kbs created by user 1 to user 2. Both users are active in Atlassian Jira and Confluence, so I can't delete user 2 (newest user without much data created) and reinvite them. What is the most efficient way to unlink user 2 from user 1s data/pages etc.
