Change Username

[Beat Mathys]

I've tried to change the username in jira from firstname to firstname.lastname.

I've made a backup of the system, change all the entries in entities.xml

from firstname to firstname.lastname with notepad++ and saved the file to the backup .zip.

as i imported the changed backup, the system setup of jira begun from scratch, with all the basic informations. 

do you have a idea, what went wrong? or is it newly possible to change the username within jira, and all tickets are still correct with the assignee  firstname.lastname?

@Beat MathysI don't think modifying record directly in backup is correct way to solve this problem.

Atlassian itself recommend bulk user related changes using Bob Swifts Command Line plugin for Jira.

If you don't want to buy this plugin, I suggest easiest way is to write simple script using Jira API. You can approach this via two methods,

1. Using ScriptRunner (plugin to execute Groovy scripts in Jira)
2. Using Rest API
