It gives me this page after upgrade:
JIRA Access Constraints
You cannot access JIRA at present.
Description Time Level Exception
The current license is too old to install this version of JIRA (6.3.11)
Edit License or proceed under Evaluation Terms
Click the "Edit License or proceed under Evaluation Terms", give me this error:
This user could not be authenticated as a JIRA Administrator
JIRA cannot proceed with the upgrade as you are not logged in as a JIRA administrator, or this version of JIRA cannot recognize administrators from the version that you have upgraded from. To proceed, log in as a JIRA administrator. If you cannot log in, override this requirement by setting the system property '-Dnon.admin.upgrade=true', then restarting JIRA.
I can't login either by admin/admin or my original jiraadmin/password. So I followed this link, still can't. https://confluence.atlassian.com/display/JIRA/Setting+Properties+and+Options+on+Startup
Can anyone help me? It's a Windows 64 bit.
