The first step that should be taken is to install the Active Roles Collector and Report Pack for the version that is being upgraded to. The Collector and Report Pack can be installed from the primary setup.exe package included in the Active Roles download files, as an optional component selected during the time of install. The setup files can be downloaded Here.
Proceed with installing and configuring the Collector and Report Pack as if it were a new installation. Steps for configuring the Collector and Report Pack, and a guidance video, can be found Here.
After the Collector and Report Pack has been successfully configured, the data from the previous database may now be imported if desired. Begin the process by launching the Active Roles Collector and Report Pack, where four options will be presented. Select the third option "Import events from an earlier database version" and proceed through the wizard.
Once the import has completed, be sure to reschedule any scheduled collections if currently in use.
