Hello Barry, thanks for your suggestions!
Importing and exporting is not our problem, the data size is not that large - we made good experiences with the TriG format here (Contexts normally do not exceed 500MB when exported). However, my question was more towards the parallel usage of OwlimSE and Owlim Lite on THE SAME MACHINE at the same time. Is this even possible? So our plan was to install Owlim Lite in parallel to Owlim SE on the same server and then import the contexts into Owlim Lite. Then we wanted to shut down the OwlimSE and migrate it... with the Owlim Lite running as a productive store as long as the migration of OwlimSE takes. Is this plan doable?
