What should I move to the new vhost? <drupal_root>/sites and <drupal_root>/profiles/translations ,that is clear. Anything more?
I don't think so. I don't know if profiles is even necessary to move. I don't *think* so.
I suppose permissions should not be big problem. These are actually two virtual hosts on the same apache server, so pure "mv" should do the job just fine. Is there anything more I should be aware of?
I don't think so. It should be easy.
