Hello,
We are upgrading a Jira from 6.3.13 to 7.13.2 can anyone suggest me the upgrade path.And also we have a Jira Service desk 7.6.1 and we are planning on combining both the applications and migrate them from our servers to AWS. Suggest me a method to achieve bringing the data to one single application. And also we have done some modifications in .jsp files and .vm files in Jira 6.3.13, so I want to know if those remain same after upgrade or do we need to rework on those files.
