I apologize for the late response.
Changing only the domain and the username of couple of users should not cause any issue but I highly recommend you to create a backup of your database before running the script that I have prepared in the attached archive.
Notice that you have to edit the script a little bit:
- Change <OLD DOMAIN> with the correct value
- Change <NEW DOMAIN> with the correct value
- For all the users with changed usernames add values following the pattern ('<old username>', '<new username>')
I have added comments in the script to help you with that.
Updating records in the database in order to keep correctly the history of the items is more complex though. I would ask you to send us the backup of your database so we can try these scripts to confirm that they will work properly before sending them to you.
I would also ask you to send us the updated script after you edit it along with the backup of your database
I'm looking forward for your response
