Hi Helen, To clarify, if you turn on Entities then existing records would remain generic Items (as they already are). That said, you could transform them into Publication entities by just setting "dspace.entity.type=Publication". Essentially, Items and Publications are nearly the same object...the only difference is that "dspace.entity.type" field value. Once you set "dspace.entity.type" to "Publication" then a normal Item will become a Publication Entity. Removing that value will turn it back into a normal Item.
In DSpace itself, generic Items and Publications look/act essentially the same in most of the User Interface. The only real difference is that Publications can be linked (via a relationship) to other Entities (like Person, OrgUnit or similar), while generic Items cannot.
