Hi,
I need to upgrade several JIRA instances in different versions (6.x and 7.x) to the latest current version (8.3.x) and wonder what intermediate steps might be necessary when using XML backups. Can an XML backup of version 6.x (i guess not) or 7.x (I guess yes) directly be imported into an empty 8.3.x instance?
I already searched with google and directly at atlassian documentation but I was not able to found something like an official compatibility matrix.
Any hint would be very much appreciated!
Best Regards,
Christian
