config.sh results in "Could not find the main class: com.atlassian.jira.configurator.Configurator."

I am upgrading JIRA to the latest version (standalone install on Solaris) and extracted the latest version along to the older version, copied the custom files and mysql connector to the new directory but I am unable to run /bin/config.sh (working correctly in the old dir).

Error:

Could not find the main class: com.atlassian.jira.configurator.Configurator. Program will exit.

Could somebody advise what I am missing?

  • Old version = atlassian-jira-6.3.10-standalone
  • New version = atlassian-jira-6.4.8-standalone

Check the java version and see if it is supported on 6.4.
