[otrs] OTRS + OCS-ng?

Hey guys, Currently I'm implementing OTRS for my company. So far, we quite enjoy to use it with some modifications and add on. But here the question goes; 1) Before OTRS system use for our company, I'm using OCS-ng which is open source for our inventory and tracking system of equipment. Here the trick; how can I extract all data inside OCS-ng and push it to all in OTRS/ITSM system?? I've been thinking this lately but serious no idea for this moment. It would be great if this can be done which using OTRS system as our core system in company. Thanks anyway for reading my mail and hope someone will reply soon. Cheers, Syareefdol.
