I own a backup file from a Confluence setup from an old company of mine that has since dissolved. I need to re-expand the wiki so I can view the content. The backup is over 1 year old, so I don't know what version of Confluence it will be compatible with. I want to know the quickest/easiest path to view this content. (I don't need a permanent setup - I just need to view the content for a couple of weeks.)
Also, I don't have the login credentials for the old account, so I need to know if that will inhibit me from having admin control over the newly expanded wiki.
