Can I use OJS instead of OCS


I installed OCS and created one conference, after shifting to another server, the emailing system of the OCS is no more working and I dont know how to fix it. My question is; can I use the OJS for publishing the conference papers, it means I install OJS as conference platform and for each conference I create a new journal and name it with the Conference title, is it possible? will these conference be indexed by PKP?

Thank you
