The data entered on the Core alumni record will dictate what data syncs to the education record, and it matches the existing record based on the School Name field.  As long as the School Name in Core and the School Name in RE match exactly, ConnectRE will update existing fields.  If they do not, it will not delete the record in Raiser's Edge, it will just add a new record:

Primary Education Record (syncs to the affiliated school itself based on role and enrollment)

Other Education Relationships

If the alumni information is entered in the Education section of the Core profile, it will not sync to the primary education record in Raiser's Edge.  Instead, a regular education record will be matched (if the School Name matches exactly) or created (if the school name is different) on the Relationships tab of the constituent record in RE.  If the records sync, the following fields will map and sync as follows:
