Hi,
in our company, I am the new Jira admin. Our Jira 8.13 is running on an Ubuntu. As Jira and Ubuntu are some versions behind, we would like to upgrade both (-> security and feature updates). What is the correct procedure? Would you do the steps in the following order?
- first copy live-system to test-system
- upgrade ubuntu on test-system
- upgrade postgress-sql on test-system
- upgrade Jira to 8.19.x on test-system
- upgrade all apps
- full index of jira
- repeat on live-system
Is there an official documentation for this? What is best practice?
