This feature was implemented on JIRA 6.1 (see release notes), and it is now possible to change project key via the JIRA UI. For the detailed instructions about this feature, you may refer to the links below:
Warning to future admins using this feature: editing the project key in JIRA does not migrate attachments nor does it create a new project key attachment directory (even for new issues after renaming).
This could be important if you have additional web services accessing files in the Jira attachment directory based off the project key (like I did).
Hello, I have changed a Next Gen project name from IT to OLDIT. The Project Key shows as OLDIT now - hwever - when I try to create a Classic Project called IT and specify using IT as the Project Key, I'm told that "Old IT Support uses this Project Key". How do I accomplish creating my new Classic Project with the Project Key I love?
