How long should it take if Jira Software (Server) needs to be upgraded from Version 7.0 to the latest Version?

Hi,

1.  Make test environment and try it first on that.
2. My recommended upgrade path is 7.0 -> 7.6 -> 7.13 -> 8.6 and if you don't have too much customizations like groovy script then weekend maintenance windows should be more than enough. My estimation is around 10 hpurs of work if nothing wrong will happen.
