What do I need to do to make the shift from KA Lite to Kolibri? Will I lose all of my stored data when I make the move?

Unfortunately, user data from KA Lite will not be transferable to Kolibri. In a classroom setting, it may be beneficial to think about the timeline of your school year and curriculum to determine the best time to start fresh with Kolibri. Depending on hardware capacity, you may choose to initially use Kolibri to explore other content sources and continue to use KA Lite until an appropriate transition point is determined.

Will it be possible to have both running in the same box?
in case they have enough hardware resources of course.
