We currently have JIRA applications (v6.3.1) running on DEV, QA and PROD environments. We are planning to upgrade all the 3 JIRA instances to 7.6.1.
All 3 environments are on Linux servers.
These JIRA applications are connected to CROWD, CRUCIBLE and FISHEYE. Before JIRA upgrade, we are supposed to upgrade the CROWD, CRUCIBLE and FISHEYE applications.
Is there any straight forward approach to upgrade JIRA from 6.3.1 to 7.6.1 ? Any documentation if provided would be appreciated.
Thanks in advance.
