we have a application link from confluence to Jira, it's setup using a FQDN like
https://jira.chicago.cme.com:8443/login

but the display name is setup as
http://jira:8080/login

whem users link in jira issues and lists all the links resolve to the display name. both DNS entries are valid and resolve, I just need the ability to rename the display name but it appears you can do this via the UI. Is this a bug of feature? Is there a database update I can run to fix this?

Any other suggestions on how to rename a valid application link, if I delete and re-add, what will happen to all the jira lists and linked in issues currently in confluence.
