Greetings. I'm a systems analyst at the university of ottawa. We have a confluence instance here and we're in a bit of a bind. The people who used to manage it are gone. I've inherited it. And my first task is to upgrade it and migrate to SSO or to our central domain LDAP. I've been looking into it, - kind of a rabbit hole because we run an older version of CentOS (6.10) with an older version of postgresql..... so - i'm thinking of building a new VM with ubuntu LTS or something and installing the new Confluence fresh on that , then using the data export / import tools in the GUI to just move over to that new server.
What landmines, roadblocks or other sleep-losers am I going to run into and how can I avoid them?
