My experience with previous installation of Jira Server was horrible customer service, very slow response, often issues take 1-2 days to even respond. Now I am facing with task of upgrading 7.13 to 8.01, and I am scared that the nightmare of dealing with jira customer service all over again. So I am willing to pay to NOT dealing with Jira customer service representative.
Do someone offer service to guarantee success upgrade without interrupt our current customers.
