Currently i have a local jira instance (on premisses) server which has version v7.3.2 #73013
I have a new server available on which i would like to install jira v8.1.0. This server will be the new jira server for our company.
So, i need to 'export' from v7.3.2 and import it in to the new 8.1.0 jira evironment.
Is there any manual/procedure that describes how to 'migrate' the old version to the new version?
