I am also interested in this. I've copied a quote from the Help saying, "In the fabric, parcels can be grouped by their plan, plat, or record of survey. Plan information is stored in the Fabric_Plans table. Each parcel has a PlanID attribute field containing the ID of the plan in the plans table. Plan information can be migrated into the parcel fabric or created during editing." It's the last sentence that I'm focusing on. I have a BookAndPage number I'd like to carry through during migration. Does anyone know, if I put a BookAndPage field in my source polygon attribute table, and a matching field in my target fabric plan table, will it migrate across? This is a new field, and not the currently existing Description field as fellj is trying to do. Although, if it works for one, it should work for the other, I'd imagine.
