We are planning to migrate our Jira/confluence/bitbucket instances to AWS EC2. With this, we will also be switching from a AD user directory, to a SAML created Jira internal directory. I am wondering if there is an easy way to ensure that ticket assignments etc remain the same, however I am guessing there is no way to do this. I was also wondering on that same line, if there is a way to automate this process of reassigning everything.
