Upgrade from RoboServer 8 to 9

I've been asked to provide upgrade instructions from RoboServer 8 to RoboServer 9 for my IT department. Adobe has instructions for installing RoboServer 9 fresh, but I can only find this one topic on migrating data:

http://help.adobe.com/en_US/RoboHelp/9.0/RoboEngine/WSbe3e657580667f14-a060fa912c5da67e0a-8000.html. Is it as simple as uninstalling v8, installing v9 fresh, then migrating the data? Any tips or documented steps would be appreciated.

Thanks.
