Migrating journal from Open Conference System to Open journal system

I was asked to receive in the OJS a journal that was running in Open Conference System. Before anything, I want to make sure there is a right and documented way to do the task maintaining all that is possible.
Any experience with this task?

OJS would require some as-yet-undeveloped features to support physical conferences:

There isn’t a direct migration path from OCS to OJS, but this might be a future recommendation.

Thank You for the feedback!
We decided to setup the journal from scratch in the OJS and used the quick submit plugin to upload the articles from previous editions. It was easier than we thought.
