I'm currently running XenForo 1.5.13 and want to upgrade.
What's the sanest way to do this?
Go direct to 2.* ? or upgrade to the most recent version of the 1.* series then upgrade from that to 2.*?
Click the Download XenForo link next to the license for the site you are upgrading. Before downloading, ensure that the Download the upgrade package only option is selected.
