I have searched the docs and community here and have not found anything younger that 14 years ago and very old versions of ALM that are related to username change.

I am thinking there has to be some way to do this and retain all links to the QC data the user has created, updated, etc.
We want to retain the linkage to all but, we are wanting to bring some usernames into our corporate standard.
We have several username that were created before the standard was implemented so, it's just a cleanup and compliance need.

I can access the DB tables to make the changes if no tool or front door method exists.
I noticed the users also have a user ID so that makes me think there is hope.

Perhaps this a feature OpenText should add as people's username does need to change from time to time for marriage or other valid reasons.
Most applications allow username changes as the User ID is the anchor that links it all together.

I saw a very OLD tool that once did this but, it so old (version 9) I would not run it.

Thanks!
