We have JIRA cloud instance in our organization which has an older version which is v1000.1045.3. due to this we are not able to find many plug-ins because they don't support older version of JIRA. Now we want to get our JIRA instance upgraded to the newest version. regarding this I raised a request to atlassian support also, but till now did not get any reply.
Can anybody please help me to upgrade my JIRA instance to version 7.3.6
