Any data in the 5XX-7XX range that is local (that is not part of the OCLC master record) needs to be moved to a protected local field. In addition, Ex Libris recommends that institution-specific data be moved out of fields 900-949 and that only consortial data stay in those fields for the Network Zone. All campus-specific data in these fields needs to be relocated or deleted.

Fields 900-949 are reserved for the Network Zone. Campuses must move all data out of this range prior to migration, regardless of whether the data is purely local or not. This includes, but is not limited to, 936 and 938 data generated during OCLC exports. The rest of the mapping can be adopted by the end of Phase 4.
